Algebra I

  • Coordinates (x, y)
  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

y = x

y = -x + 4

Step 2: Solve for x

Substitution

  1. Substitute in y:                                                                                                x = -x + 4
  2. [Addition Property of Equality] Add x on both sides:                                    2x = 4
  3. [Division Property of Equality] Divide 2 on both sides:                                x = 2

Step 3: Solve for y

  1. Define original equation:                                                                                y = x
  2. Substitute in x:                                                                                                y = 2
