  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

-x + 4y = -8

-5x - 4y = -16

Step 2: Solve for x

Elimination

  1. Combine equations:                     -6x = -24
  2. Isolate x:                                        x = 4

Step 3: Solve for y

  1. Define equation:                   -x + 4y = -8
  2. Substitute in x:                      -4 + 4y = -8
  3. Isolate y term:                       4y = -4
  4. Isolate y:                                y = -1
