Question

What is the value of x that satisfies the equation $\frac{x-1}{3}=\frac{2x-6}{4}$

• A. $5$
• B. $7$
• C. $8$
• D. $16$

Answer 1

The correct option is B $7$

Consider $\frac{(x-1)}{3}=\frac{(2x-6)}{4}$, by cross multiplying we get,

$4(x-1)=3(2x-6)$

$\Rightarrow 4x-4=6x-18$

$\Rightarrow 6x-4x=18-4$

$\Rightarrow 2x=14$

$\Rightarrow x=7$

Hence, option B is correct.
