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?

x – 4 = –7

x + 4 = –7

–x – 4 = 7

x + 4 = 7

Answer 5

|x-4| = 7
+4 +4
^^Add four to each side, so that the "x" is alone on one side and the whole number on the other side.^^
Now you have...
x= 7+4
Simplify it by adding both numbers...
So x= 11
