The absolute value of something is it´s distance away from zero. Now, we need to make everything positive in the equation.
Given: absval 5x+10=-7
Simplify: |5x+10=-7|
Abs Val: 5x+10=7
Now, we have the absolute value of 5x+10=-7
Now, to simplify so we can use this EXAMPLE to display the true answer.
Subtraction: 5x=-17
Division: x=-17/5
Simplify: x=-3.4
Absolute Value: x=3.4
Answer: x=3.4
