Step-by-step explanation:

<u>Step 1: Define</u>

<u /> $\displaystyle \frac{a}{-7} - 7 = 5$ <u />

<u />

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

Addition Property of Equality: $\displaystyle \frac{a}{-7} - 7 + 7 = 5 + 7$
[Simplify] Add: $\displaystyle \frac{a}{-7}= 12$
Multiplication Property of Equality: $\displaystyle -7 \cdot \frac{a}{-7} = 12 \cdot -7$
[Simplify] Multiply: $\displaystyle a = -84$

<u>Step 3: Check</u>

<em>Plug in a into the original equation to verify it's a solution.</em>

Substitute in <em>a</em>: $\displaystyle \frac{-84}{-7} - 7 = 5$
[Frac] Divide: $\displaystyle 12 - 7 = 5$
Subtract: $\displaystyle 5 = 5$

Here we see that 5 does indeed equal 5.

∴ a = -84 is the solution to the equation.
