  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

-5x + 6y = 55

4x + 3y = 34

Step 2: Rewrite Systems

4x + 3y = 34

  1. Multiply everything by -2:                    -8x - 6y = -68

Step 3: Redefine Systems

-5x + 6y = 55

-8x - 6y = -68

Step 4: Solve for x

Elimination

  1. Combine equations:                    -13x = -13
  2. Divide -13 on both sides:             x = 1

Step 5: Solve for y

  1. Define equation:                    4x + 3y = 34
  2. Substitute in x:                       4(1) + 3y = 34
  3. Multiply:                                  4 + 3y = 34
  4. Isolate y term:                        3y = 30
  5. Isolate y:                                 y = 10
