Question

If $\frac{2}{5}(5x+1)+\frac{3}{5}=1$, then what is the value of 5 x?

• A. $\frac{-1}{5}$
• B. $1$
• C. $0$
• D. $\frac{1}{5}$

Answer 1

The correct option is C $0$

$\frac{2}{5}(5x+1)+\frac{3}{5}=1$

$\Rightarrow$ $2x+\frac{2}{5}+\frac{3}{5}=1$

$\Rightarrow$ $2x+\frac{5}{5}=1$

$\Rightarrow$ $2x+1=1$

$\Rightarrow$ $2x=0$

$\therefore$ $x=0$

$\therefore$ $x=0$ then, $5x=0$
