  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

-2x - y = 0

10x + y = -8

Step 2: Solve for x

Elimination

  1. Combine equations:                         8x = -8
  2. Isolate x:                                            x = -1

Step 3: Solve for y

  1. Define equation:                    -2x - y = 0
  2. Substitute in x:                       -2(-1) - y = 0
  3. Multiply:                                  2 - y = 0
  4. Isolate y term:                        -y = -2
  5. Isolate y:                                 y = 2

Answer:

Step-by-step explanation:

-2x -y = 0

10x+ y= -8

8x = -8

x = -1

-10 + y = -8

y = 2
