Question

Below are the steps to solve an equation:

Step 1: |x − 4| + 1 = 8
Step 2: |x − 4| = 8 − 1
Step 3: |x − 4| = 7

Which of the following is a correct next step to solve the equation?
A x − 4 = −7
B x + 4 = −7
C −x − 4 = 7
D x + 4 = 7

Answer 1

none of it is correct because |x-4| = 7 is an absolute equation which can't be subtract or add we have to make 2 equations from it x-4 = 7 and x-4 = -7 and the solve.

Answer 2

you would use the distributive property to solve the equation to remove exponets then to get your final equation.
