<em>Identify</em>

7/8y + 1/2 = 1 1/5

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

  1. Convert to improper fraction:                                                                          7/8y + 1/2 = 6/5
  2. [Subtraction Property of Equality] Subtract 1/2 on both sides:                       7/8y = 7/10
  3. [Division Property of Equality] Divide 7/8 on both sides:                              y = 4/5
