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

$⟹\bold{40 - 48m + 80 = - 40m + 80}$

$⟹\bold{40 + 80 - 48m = - 40m + 80}$

$⟹\bold{120 - 48m = - 40m + 80}$

$⟹\bold{120 - 80 = - 40m + 48m}$

$⟹\bold{40 = 8m}$

$⟹\bold{\red{m = \frac{40}{8} = 5}}$

$\mathcal{CHECK:-}$

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

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

$⟹\bold{40 - 16(10) = - 10(12)}$

$⟹\bold{40 - 160 = - 120}$

$⟹ \bold{- 120 = - 120}$

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

════════════XXX═════════════

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

⟹\bold{40 - 48m + 80 = - 40m + 80}⟹40−48m+80=−40m+80

⟹\bold{40 + 80 - 48m = - 40m + 80}⟹40+80−48m=−40m+80

⟹\bold{120 - 48m = - 40m + 80}⟹120−48m=−40m+80

⟹\bold{120 - 80 = - 40m + 48m}⟹120−80=−40m+48m

⟹\bold{40 = 8m}⟹40=8m

⟹\bold{\red{m = \frac{40}{8} = 5}}⟹m=

8

40

=5

\mathcal{CHECK:-}CHECK:−

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

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

⟹\bold{40 - 16(10) = - 10(12)}⟹40−16(10)=−10(12)

⟹\bold{40 - 160 = - 120}⟹40−160=−120

⟹ \bold{- 120 = - 120}⟹−120=−120

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