Algebra I

  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

y = 2x

x = -y + 6

Step 2: Solve for y

Substitution

  1. Substitute in x:                     y = 2(-y + 6)
  2. Distribute 2:                         y = -2y + 12
  3. Isolate y terms:                    3y = 12
  4. Isolate y:                               y = 4

Step 3: Solve for x

  1. Define equation:                    x = -y + 6
  2. Substitute in y:                       x = -4 + 6
  3. Add:                                        x = 2
