Answer 1

Answer:  2x + 15 = 243

                          x = $114

Step-by-step explanation:

Gas Tank: $15

Matthew: x

Devin: x

Gas Tank + Matthew + Devin = Total

       15      +       x        +     x    =  243

                                         2x   =  228

                                           x   =   114
