  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

<u>Step 1: Define Systems</u>

-2x - y = 0

10x + y = -8

<u>Step 2: Solve for </u><em><u>x</u></em>

<em>Elimination</em>

  1. Combine equations:                         8x = -8
  2. Isolate <em>x</em>:                                            x = -1

<u>Step 3: Solve for </u><em><u>y</u></em>

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