Answer:

(3, 2)

General Formulas and Concepts:

Pre-Algebra

  • Order of Operations: BPEMDAS
  • Equality Properties

Algebra I

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

Step-by-step explanation:

Step 1: Define systems

2x + 8y = 22

8x - 8y = 8

Step 2: Solve for x

Elimination

  1. Add 2 equations together:                    10x = 30
  2. Divide 10 on both sides:                         x = 3

Step 3: Solve for y

  1. Define original equation:                    8x - 8y = 8
  2. Substitute in x:                                     8(3) - 8y = 8
  3. Multiply:                                                24 - 8y = 8
  4. Subtract 24 on both sides:                 -8y = -16
  5. Divide -8 on both sides:                      y = 2

Step 4: Graph systems

Check the systems.
