This is lesson 1.4. This is an example to that alarm monitoring progress probably number 6 that I'd given class. Period I don't know I love you. We're able to get the since your note. I'm going to add it to my website. So here we go. Okay, you can see here. We have the absolute value he plays in and there's a lot going on on the west side, so it's so much easier. Just simple. Left side, but we can get the absolute value by itself and then solve it from there immediately when we see this negative. We think it's no solution. The docs not the case because just because of an egg 11, I'm here doesn't mean that the absolute value. Bye. Dozens of people making love. It's me. We have to multiply the absolute value once we figure out what exit x -2 we have to subtract $0.03 and then after Boots and then it would equal -11 so we cannot assume that it's going to be a no solution right away based on what we see the first step is to ask 3. Go side as we would do an inverse operations to solve a problem. We're looking for adding and subtracting first Denver left with this -2 times the Value of 5x - 1 and this would equal -8.  The next thing to do is to do the inverse of x -2 and device. Hey, Megan with you since about this time. I know you you need quality properties of division the -2 cancel out. I notice it's an agency does not touch anything inside the absolute value symbol because I was a grouping symbol so does not affected by this -2. side, we're simply I'm doing the multiplication by the inverse operation we left the absolute value of 5x - 1  equals Papa  and now we can find this my simpler version. Value appraising some be much easier to talk so we're going to attack this one like we did with our regular ones earlier today. Some number can 5 - 1 have absolute value of 4 so what we're looking for we want this expression when we're done with it. After we figure out what the Texas and we multiply 25 and we subtract 1 from it. We need this whole thing to equal 4 or -4 cuz those are the two? hi, Kirsten f*** would have an absolute value of 4 which you before distance of the rate of 0 the problem is is we don't know exactly what exit b 2 x 5 mm to check when we could do a lot of guessing check, but we're going to take this expression out by next -5 and tell her cells that we want to fix pressing 2. For when we're done, so that we would have a 4 in the absolute value symbol that would in fact people for we also want that expression. equal a -4 when we're done because inside he's absolute values if we have -4 that would also give us the 4 distance away from So then we go into our two separate linear equations, and we applied quality properties. solve for the vehicle And we notice in this case that we will end up with xe. 1 + x equals -3 so this is a little tricky to do a mental checklist because it's such a busy equation so I recommend. Knoxville Written checks Id  So that you can be sure that these answers are correct, so we will take our original absolute. Asian, and we will check both answer so let's start with the first solution, and we'll grab this one. easy number to shop then make sure that we wrote the entire original occasion to substituting. Solution and for an all we do is apply order of operations from Dr. James, and we try to simplify with insight Arc roofing symbols 1st. I'm at this point now. We have to actually apply the the multiplication property here, and we have an absolute value of 4/2. What is the absolute value for it is 4 so we can rewrite this to megan 2 x 4 - 3 equals -11 and -210 for the negative? -8 - 3 is a -11 so that in fact does work so we can check the fat ones off now. We're Hi, the same concept to our neck solution writing to your recently craven. Which was -2 absolute value. See again. 5 x -1 absolute value, I'm free And I'm going to apply. the Solution -3/5 I'm 4x. I'm a man apply order of operations to simplify. Hoping that when I'm done, and if I have the correct solution that winx is n***** Lisa this side will in fact equal -11 so let's apply. Nation simple thing with insight grouping simple 1st. I have 5 times -3/5 so making 5 a fraction I can cross cancel the 5. Which leaves me with -3 minus one in the absolute bye symbols - 3 equals -11?  this -4 an absolute bye symbol -3 equals 11, so the absolute value of -4 isn't zack positive 4 so we can rewrite this is nate. Gigi's positive for cuz that's what -2 by making 4 equals -3 equals -11 and then this becomes? 8 - 3 again  And we have -11 equals -11.
