Answer: 2x-7 + 2x-12 = 25

                  combine like terms

                  4x-19=25

                         +19

                   4x=44

                  4      /4

divide on both sides

and X=11

now you can put X back into the equation.

AB= 2(11) -12... which ends up equaling 10.

you´re welcome
