  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

y = 2x - 4

y = -x + 5

Step 2: Solve for x

Substitution

  1. Substitute in y:                    2x - 4 = -x + 5
  2. Add x to both sides:           3x - 4 = 5
  3. Add 4 to both sides:           3x = 9
  4. Isolate x:                              x = 3

Step 3: Solve for y

  1. Define equation:                    y = -x + 5
  2. Substitute in x:                       y = -3 + 5
  3. Add:                                        y = 2
