Question

If $x$ is a solution of the algebraic equation $\frac{x}{7}-5=10$, then $x=$

• A. $170$
• B. $105$
• C. $210$

Answer 1

The correct option is B $105$

Given algebraic equation, $\frac{x}{7}-5=10$

Let's solve this equation step by step.

Step 1: Adding $5$ both sides,

$\Rightarrow \frac{x}{7}-5+5=10+5$

$\Rightarrow \frac{x}{7}=15$

Step 2: Multiplying both the sides by $7$,

$\Rightarrow \frac{x}{7}\times 7=15\times 7$
$\Rightarrow x=105$
