Answer: x = -1 or 15
Step-by-step explanation:
If the absolute value equals 8, the value of x - 7 can either be -8 or 8.
We first solve for when it is equal to -8:
x - 7 = -8
We can add 7 to both sides:
x = -1
Now we can solve for when it's equal to 8:
x - 7 = 8
We can add 7 to both sides:
x = 15
7+8 = 15
so inverse that
15-7=8
x = 15
