Question

Solve the following equations and check your results. If $\frac{2x}{3}+1=\frac{7x}{15}+3$, then $x$ is equal to

• A. $10$
• B. $12$
• C. $14$
• D. $16$

Answer 1

Answer: (A)

$10$

Given, $\frac{2x}{3}+1=\frac{7x}{15}+3$

By taking L.C.M., we get

$5(2x+3)=7x+45$

$\Rightarrow 10x+15=7x+45$

$\Rightarrow 3x=30$

$\Rightarrow x=10$
