Question:
If $\frac{2}{5} x-2=5-\frac{3}{5} x$, then $x=--$
Solution:
7
Given, $\frac{2}{5} x-2=5-\frac{3}{5} x$
$\Rightarrow$ $\frac{2 x}{5}+\frac{3 x}{5}=5+2\left[\right.$ transposing $-\frac{3 x}{5}$ to LHS and $-2$ to RHS $]$
$\Rightarrow$ $\frac{5 x}{5}=7$
$\Rightarrow$ $x=7$
Hence, the value of $x$ is 7 .
