$⟹\bold{40 - 16(3m - 5) = - 10(4m - 8)}$

$⟹\bold{40 - 48m + 80 = - 40m + 80}$

$⟹\bold{40 + 80 - 48m = - 40m + 80}$

$⟹\bold{120 - 48m = - 40m + 80}$

$⟹\bold{120 - 80 = - 40m + 48m}$

$⟹\bold{40 = 8m}$

$⟹\bold{\red{m = \frac{40}{8} = 5}}$

$\mathcal{CHECK:-}$

$⟹\bold{40 - 16(3(5) - 5) = - 10(4(5) - 8)}$

$⟹\bold{40 - 16(15 - 5) = - 10(20 - 8)}$

$⟹\bold{40 - 16(10) = - 10(12)}$

$⟹\bold{40 - 160 = - 120}$

$⟹ \bold{- 120 = - 120}$

Therefore,L.H.S=R.H.S
