# How do you solve d/-4+3=15?

Sep 25, 2016

$d = - 48$

#### Explanation:

To eliminate the fraction on the left side along with the leading negative sign, multiply $\textcolor{b l u e}{\text{all terms}}$ by -4.

${\cancel{- 4}}^{1} \times \frac{d}{\cancel{- 4}} ^ 1 + \left(- 4 \times 3\right) = \left(- 4 \times 15\right)$

$\Rightarrow d - 12 = - 60$

To solve for d, add 12 to both sides.

$d \cancel{- 12} \cancel{+ 12} = - 60 + 12$

$\Rightarrow d = - 48 \text{ is the solution to the equation.}$
