Question

Solve the equations:

(2) 8q – 2 = 3q + 18

Answer 1

8q – 2 = 3q + 18
Subtracting 3q from both sides, we obtain:
8q – 2 – 3q = 3q + 18 – 3q
$\Rightarrow$5q – 2 = 18
Adding 2 to both sides, we obtain:
5q – 2 + 2 = 18 + 2
$\Rightarrow$5q = 20
Dividing both the sides by 5, we obtain:
$$\begin{gathered} \frac{5q}{5}=\frac{20}{5} \\ \Rightarrow q=4 \end{gathered}$$
