  • Solving systems of equations by substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

-3x - 3y = 3

y = -5x - 17

Step 2: Solve for x

Substitution

  1. Substitute in y:                    -3x - 3(-5x - 17) = 3
  2. Distribute -3:                       -3x + 15x + 51 = 3
  3. Combine like terms:           12x + 51 = 3
  4. Isolate x term:                     12x = -48
  5. Isolate x:                              x = -4

Step 3: Solve for y

  1. Define equation:                    y = -5x - 17
  2. Substitute in x:                       y = -5(-4) - 17
  3. Multiply:                                  y = 20 - 17
  4. Subtract:                                 y = 3
