  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

x - y = -2

3x - y = 2

Step 2: Rewrite Systems

x - y = 2

  1. Add y to both sides:                    x = 2 + y

Step 3: Redefine Systems

x = 2 + y

3x - y = 2

Step 4: Solve for y

Substitution

  1. Substitute in x:                    3(2 + y) - y = 2
  2. Distribute 3:                         6 + 3y - y = 2
  3. Combine like terms:           6 + 2y = 2
  4. Isolate y term:                     2y = -4
  5. Isolate y:                              y = -2

Step 5: Solve for x

  1. Define:                         x - y = 2
  2. Substitute in y:            x - (-2) = 2
  3. Simplify:                       x + 2 = 2
  4. Isolate x:                      x = 0
