Following the definition of the absolute function, we have:

|2x-20|=2x-20 when 2x-20≥0, and

|2x-20|=-(2x-20) when 2x-20<0

and a similar relationship exists for the right hand side.

For this particular case, solving the following equations for x will cover all cases:

2x-20=9x+15 ...(1), and

2x-20=-(9x+15) ...(2)

The following graphic depicts the solutions to (1) and (2):
