Question

Find the value of $x$ in $\frac{2x+4}{8x}=4$

• A. $\frac{15}{2}$
• B. $\frac{2}{15}$
• C. $\frac{-2}{15}$
• D. None

Answer 1

Answer: (B)

$\frac{2}{15}$

$\frac{2x+4}{8x}=4$

Multiply both sides by $8x$,

$⟹\left(\frac{2x+4}{8x}\right)\times 8x=4\times 8x$

$⟹2x+4=4\times 8x$

$⟹2x+4=32x$
$⟹30x=4$

$\therefore x=\frac{2}{15}$
