  • Solving systems of equations using substitution/elimination
  • Solving systems of equations by graphing

Step-by-step explanation:

Step 1: Define systems

2x + 4y = -12

y = 4x - 3

Step 2: Solve for x

Substitution

  1. Substitute in y:                              2x + 4(4x - 3) = -12
  2. Distribute 4:                                   2x + 16x - 12 = -12
  3. Combine like terms:                     18x - 12 = -12
  4. Isolate x term:                               18x = 0
  5. Isolate x:                                        x = 0

Step 3: Solve for y

  1. Define original equation:                    y = 4x - 3
  2. Substitute in x:                                     y = 4(0) - 3
  3. Multiply:                                                y = 0 - 3
  4. Subtract:                                               y = -3

Step 4: Graph systems
