Question 9

Q10) 3m=5m-\frac{8}{5}

Solution:

3m=5m-\frac{8}{5}

\Rightarrow3m-5m=-\frac{8}{5}

\Rightarrow\ -2m=-\frac{8}{5}

\Rightarrow m=\frac{-8}{5\times\left(-2\right)}

\Rightarrow\ m=\frac{4}{5}

To check:

3m=5m-\frac{8}{5}

\Rightarrow3\times\frac{4}{5}=5\times\frac{4}{5}-\frac{8}{5}

\Rightarrow\ \frac{12}{5}=4-\frac{8}{5}

\Rightarrow\frac{12}{5}=\frac{20-8}{5}

\Rightarrow\ \frac{12}{5}=\frac{12}{5}

L.H.S. = R.H.S.

Hence, it is correct.
