What is the Pythagorean Theorem? 

a² + b^{2 =} c²

200

Solve:

5x + 12 - 2x = -15

5x + 12 - 2x = -15

                                 3x + 12 = -15 

                                       -12     -12

                                         3x = -27

                                          /3     /3

              x = -9

5(y + 8) = 60

5(y + 8) = 60

5y + 40 = 60

                                      -40    -40

                                        5y = 20

                                        /5     /5

        y = 4
