Question

Solve each equation. Check your solution.

$-4a=48$

Step-by-Step Solution

Answer

The required solution is $a=-12$.

Step 1. Write the given information.

The given equation is:

$-4a=48$

Step 2. Calculation.

Consider the given equation

$\begin{array}{l}-4a=48\\ a=-\frac{48}{4}\text{ [Divide both sides by 4]}\\ a=-12\end{array}$

Step 3. Checking solution.

Substitute $a=-12$ in the given equation to check:

$$\begin{gathered} -4a=48 \\ -4\left(-12\right)=48 \\ 48=48 \end{gathered}$$

Hence, proved.
