Answer:

(-1, 4)

General Formulas and Concepts:

Pre-Algebra

  • Order of Operations: BPEMDAS
  • Equality Properties

Algebra I

  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define systems

10x + 6y = 14

-x - 6y = -23

Step 2: Solve for x

Elimination

  1. Add 2 equations together:                    9x = -9
  2. Divide 9 on both sides:                          x = -1

Step 3: Solve for y

  1. Define original equation:                    -x - 6y = -23
  2. Substitute in x:                                     -(-1) - 6y = -23
  3. Multiply:                                                1 - 6y = -23
  4. Subtract 1 on both sides:                     -6y = -24
  5. Divide -6 on both sides:                      y = 4
