Answer:
2 solutions
Explanation:
the absolute value function always gives a positive result, however the expression inside can be positive or negative , then
x + 1 = 5 ( subtract 1 from both sides )
x = 4 ( multiply both sides by 2 )
x = 8 ← 1 solution
--------------------------------
or
- (
x + 1) = 5
-
x - 1 = 5 ( add 1 to both sides )
-
x = 6 ( multiply both sides by - 2 )
x = - 12 ← 2nd solution
