Question

How do you solve `abs(2x+13)=28`?

Answer 1

The solution is `x = 7.5, -20.5`

Explanation:

Removing the absolute value function and solving these two equations provide the answer:

`2x + 13 = 28 =>`2x + 13 - 13 = 28 - 13 => 2x = 15 => x = 7.5#

`2x + 13 = -28 => 2x + 13 - 13 = -28 - 13 => 2x = -41 => x = -20.5`
