Question:
Solve the following equation and verify your answer:
$\frac{5 x-7}{3 x}=2$
Solution:
$\frac{5 x-7}{3 x}=2$
or $6 \mathrm{x}=5 \mathrm{x}-7$ (After c ross multiplication)
or $6 \mathrm{x}-5 \mathrm{x}=-7$
or $\mathrm{x}=-7$
$\therefore \mathrm{x}=-7$ is the solution of given equation.
Check:
Substituting $x=-7$ in the given equation, we get:
L. H.S $=\frac{5 \times(-7)-7}{.3(-7)}=\frac{-35-7}{-21}=\frac{-42}{-21}=2$
R. H.S. $=2$
$\therefore$ L. H.S. $=$ R. H. S. for $x=-7$.
