Explanation: •You are basically looking for 2 values of X •First X will be to the left of -3 •Second X will be to the right of -3 •Both X’s will be 7 units away from -3, if you do this correctly you will find that x to the left is equal to -10 and x to the right is equal to 4
You can develop the absolute value equation as follows: X=-3 -7 Or X=-3+7
Add 3 to both sides of the equation to get : X+3=7 X+3=-7
This fits the basic definition of an absolute value equation that states if |x|=y , then x=y or x=-y
