Solving systems of equations using substitution/eliminationSolving systems of equations by graphing

Step-by-step explanation:

Step 1: Define systems

-5x - 3y = 12

y = x - 12

Step 2: Solve for x

Substitution

Substitute in y:                              -5x - 3(x - 12) = 12Distribute -3:                                 -5x - 3x + 36 = 12Combine like terms:                     -8x + 36 = 12Isolate x term:                               -8x = -24Isolate x:                                        x = 3

Step 3: Solve for y

Define original equation:                    y = x - 12Substitute in x:                                     y = 3 - 12Subtract:                                               y = -9

Step 4: Graph systems
