|x| – 7 = 8 plz me x = –1 or 1 x = 1 x = 15 x = –15 or 15

x = –15 or 15

Step-by-step explanation:

|x| – 7 = 8

We need to isolate the absolute value.

Add 7 to each side

|x| – 7+7 = 8+7

|x|  = 15  

Now to get rid of the absolute values, we take what is inside the absolute values and set it equal to the right hand side.  Remember we set it equal to the positive amount and the negative amount.

x=+15 and x=-15
