Question

Solve the linear equation:

$\frac{3x}{5x-5}=-1$

• A. $\frac{3}{10}$
• B. $7$
• C. $\frac{5}{8}$
• D. $12$

Answer 1

Answer: (C)

$\frac{5}{8}$

Given, $\frac{3x}{5x-5}=-1$

On cross multiplying, we get

$-1(5x-5)=3x$

$\Rightarrow -5x+5=3x$

Bringing $x$ terms to one side, we get

$3x+5x=5$

$\Rightarrow 8x=5$

$\Rightarrow x=\frac{5}{8}$
