Question:
Solve the following equation and verify your answer:
$\frac{6}{2 x-(3-4 x)}=\frac{2}{3}$
Solution:
$\frac{6}{2 \mathrm{x}-(3-4 \mathrm{x})}=\frac{2}{3}$
or $\frac{6}{6 \mathrm{x}-3}=\frac{2}{3}$
or $12 \mathrm{x}-6=18 \quad$ [After c ross multiplication]
or $12 \mathrm{x}=18+6$
or $\mathrm{x}=\frac{24}{12}$
or $\mathrm{x}=2$
Thus, $\mathrm{x}=2$ is the solution of the given equation. Check:
Substituting $x=2$ in the given equation, we get:
L.H.S. $=\frac{6}{2 \times 2-(3-4 \times 2)}=\frac{6}{9}=\frac{2}{3}$
R.H.S. $=\frac{2}{3}$
$\therefore$ L.H.S. $=$ R.H. S. for $\mathrm{x}=2$.
