Solution

The correct option is C $8$
Given, $2 x - 1 = 6$
$\Rightarrow 2 x = 7$
$\Rightarrow x = 3.5$
$\Rightarrow$ putting the value of $x$ in $2 x + 1$
$\Rightarrow 2 x + 1$
$\Rightarrow 2 \times 3.5 + 1$
$\Rightarrow 7 + 1 = 8$

\frac{x - 2}{6} - \frac{2 x + 1}{10} = \frac{2 x - 3}{15}

\frac{2 x + 1}{3 x - 2} = \frac{9}{10}

Solve : $\frac{2 x}{3} - \frac{x - 1}{6} + \frac{7 x - 1}{4} = 2 \frac{1}{6} .$

Hence, find the value of 'a', if $\frac{1}{a} + 5 x = 8.$
