Question

What are the steps to be followed in order to solve this equation?

$\frac{x+3}{8}=\frac{1}{4}$

• A. Subtract 3 from both the sides and then multiply both sides by 8.
• B. Multiply both sides by 8 and then subtract 3 from both sides.
• C. Divide both the sides by 3 and then add 8 to both sides.
• D. Add 3 to both the sides and then divide both the sides by 8.

Answer 1

The correct option is B Multiply both sides by 8 and then subtract 3 from both sides.

Given,

$\frac{x+3}{8}=\frac{1}{4}$

On multiplying 8 on the both sides, we get,

$8\times \frac{x+3}{8}=8\times \frac{1}{4}\Rightarrow x+3=2$

Subtracting 3 from both sides, we get,

$x+3-3=2-3$
$x=-1$
