Answer 2

$\dfrac{\text{a}}{4} - 5 = - 8$

We're trying to get "a" onto its own side of the equal sign, so let's start out by adding 5 to both sides of the equal sign.

$\dfrac{\text{a}}{4} -5 + 5 = -8 + 5$

Simplify.

$\dfrac{\text{a}}{4} = -3$

Now, we need to get rid of "4" as the denominator (the bottom number in a fraction). So to do so, we must multiply both sides by 4.

$\dfrac{\text{a}}{4}\times4=-3\times4$

Simplify.

$\text{a} = -12$

So, our answer = -12
