  • Coordinates (x, y)
  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

-4x + 16 = y

2x - 32 = 2y

Step 2: Solve for x

Substitution

  1. Substitute in y:                                                                                                2x - 32 = 2(-4x + 16)
  2. Distribute 2:                                                                                                    2x - 32 = -8x + 32
  3. [Addition Property of Equality] Add 8x on both sides:                                10x - 32 = 32
  4. [Addition Property of Equality] Add 32 on both sides:                                10x = 64
  5. [Division Property of Equality] Divide 10 on both sides:                              x = 32/5

Step 3: Solve for y

  1. Define original equation:                                                                               -4x + 16 = y
  2. Substitute in x:                                                                                                -4(32/5) + 16 = y
  3. Multiply:                                                                                                           -128/5 + 16 = y
  4. Add:                                                                                                                -48/5 = y
  5. Rewrite/Rearrange:                                                                                           y = -48/5
