Question

Solve for x:
$\frac{x}{7}+\frac{2}{7}=\frac{6}{7}$

• A. 1
• B. 4
• C. 14
• D. 9

Answer 1

The correct option is B 4

The given equation is,
$\frac{x}{7}+\frac{2}{7}=\frac{6}{7}$

Transposing $\frac{2}{7}$ from LHS to RHS, we get,
$\frac{x}{7}=\frac{6}{7}-\frac{2}{7}$
$\frac{x}{7}=\frac{6-2}{2}$
$\frac{x}{7}=\frac{4}{7}$

Transposing $7$ from LHS to RHS, we get,
$x=\frac{4\times 7}{7}$
$x=4$

So, the value of $x$ is 4.
