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

Step-by-step explanation:

Step 1: Define Systems

16x + 14y = 8

-63x - 14y = 133

Step 2: Solve for x

Elimination

  1. Combine 2 equations:                    -47x = 141
  2. Divide -47 on both sides:               x = -3

Step 3: Solve for y

  1. Define original equation:                    16x + 14y = 8
  2. Substitute in x:                                     16(-3) + 14y = 8
  3. Evaluate multiplication:                       -48 + 14y = 8
  4. Add 48 on both sides:                        14y = 56
  5. Divide 14 on both sides:                      y = 4

Step 4: Graph Systems
