Step-by-step explanation:

Step 1: Define Systems

y = 3

y = -3x + 6

Step 2: Solve for x

Substitute in y:                                                                                                 3 = -3x + 6[Subtraction Property of Equality] Subtract 6 on both sides:                      -3 = -3x[Division Property of Equality] Divide -3 on both sides:                                1 = xRewrite/Rearrange:                                                                                        x = 1

Step 3: Solve for y

Define original equation:                                                                               y = -3(1) + 6Multiply:                                                                                                           y = -3 + 6Add:                                                                                                                 y = 3
