Question

The solution of the equation $\frac{3}{7}+x=\frac{17}{7}$ is ______.

• A. 2
• B. 3
• C. 4
• D. 5

Answer 1

The correct option is A 2

$\frac{3}{7}+x=\frac{17}{7}$

⇒ $x=\left(\frac{17}{7}\right)–\left(\frac{3}{7}\right)$
⇒ $x=\frac{14}{7}$
⇒ $x=2$

Hence, the solution of the equation is 2.
