  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

y = -x + 1

y = 4x - 14

Step 2: Rewrite Systems

y = 4x - 14

  1. Multiply everything by -1:                    -y = -4x + 14

Step 3: Redefine Systems

y = -x + 1

-y = -4x + 14

Step 4: Solve for x

Elimination

  1. Combine equations:                    0 = -5x + 15
  2. Isolate x term:                               -15 = -5x
  3. Isolate x:                                       3 = x
  4. Rewrite:                                        x = 3

Step 5: Check

  1. Define equation:                    y = -x + 1
  2. Substitute in x:                       y = -3 + 1
  3. Add:                                        y = -2
