  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

y = 4x - 8

x - 2y = 16

Step 2: Solve for x

Substitution

  1. Substitute in y:                    x - 2(4x - 8) = 16
  2. Distribute -2:                       x - 8x + 16 = 16
  3. Combine like terms:           -7x + 16 = 16
  4. Isolate x term:                     -7x = 0
  5. Isolate x:                              x = 0

Step 3: Solve for y

  1. Define equation:                    y = 4x - 8
  2. Substitute in x:                       y = 4(0) - 8
  3. Multiply:                                  y = 0 - 8
  4. Subtract:                                 y = -8
