Answer:
x = - 25
Explanation:
the absolute value function always gives a positive value , however , the expression inside the bars can be positive or negative, that is
| - a | = | a | =a
given
| x + 10 | = 15 , then
x + 10 = 15 ( subtract 10 from both sides )
x = 5
OR
-(x + 10) = 15
- x - 10 = 15 ( add 10 to both sides )
- x = 25 ( multiply both sides by - 1 )
x = - 25
solutions are x = 5 , x = - 25
