  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

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

x - y = -1

3x + 5y = 21

<u>Step 2: Rewrite Systems</u>

x - y = -1

  1. Add <em>y</em> to both sides:                    x = y - 1

<u>Step 3: Redefine Systems</u>

x = y - 1

3x + 5y = 21

<u>Step 4: Solve for </u><em><u>y</u></em>

<em>Substitution</em>

  1. Substitute in <em>x</em>:                              3(y - 1) + 5y = 21
  2. Distribute 3:                                   3y - 3 + 5y = 21
  3. Combine like terms:                     8y - 3 = 21
  4. Add 3 to both sides:                     8y = 24
  5. Divide 8 on both sides:                y = 3
