Substitution

  1. Substitute in y: 2x - 7 = -x + 5
  2. [Addition Property of Equality] Isolate x terms: 3x - 7 = 5
  3. [Addition Property of Equality] Isolate x term: 3x = 12
  4. [Division Property of Equality] Isolate x: x = 4

Step 3: Solve for y

  1. Define original equation: y = -x + 5
  2. Substitute in x: y = -4 + 5
  3. Add: y = 1
