  • Solving systems using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

y = 2x

-3x - 15 = y

Step 2: Solve for x

  1. Substitute in y:                    2x = -3x - 15
  2. Isolate x terms:                   5x = -15
  3. Isolate x:                              x = -3

Step 3: Solve for y

  1. Define equation:                     y = 2x
  2. Substitute in x:                        y = 2(-3)
  3. Multiply:                                   y = -6
