Verified

Answer

The solution of the given equation $a = 5$ .

1Step 1. Isolate the variable.

$\begin{array}{l} 2 a - 6 = 4 \\ 2 a = 4 + 6 \\ 2 a = 10 \end{array}$

2Step 2. Solve for the variable.

$\begin{array}{l} a = \frac{10}{2} \\ a = 5 \end{array}$

3Step 3. Check the solution by putting the value of a into the given equation.

$\begin{array}{l} 2 a - 6 = 4 \\ 2 (5) - 6 = 4 \\ 10 - 6 = 4 \\ 4 = 4 \end{array}$

Hence, proved.
