Algebra I

  • Equality Properties
  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

y = x - 4

y = 4x + 2

Step 2: Solve for x

Substitution

  1. Substitute in y:                    x - 4 = 4x + 2
  2. Isolate x terms:                   -4 = 4x + 2
  3. Isolate x term:                     -6 = 4x
  4. Isolate x:                              -3/2 = x
  5. Rewrite:                               x = -3/2

Step 3: Solve for y

  1. Define equation:                    y = x - 4
  2. Substitute in x:                       y = -3/2 - 4
  3. Subtract:                                 y = -11/2
