══════════XXX═════════════

⟹40 - 16(3m - 5) = - 10(4m - 8)⟹40−16(3m−5)=−10(4m−8)

⟹40 - 48m + 80 = - 40m + 80⟹40−48m+80=−40m+80

⟹40 + 80 - 48m = - 40m + 80⟹40+80−48m=−40m+80

⟹120 - 48m = - 40m + 80⟹120−48m=−40m+80

⟹120 - 80 = - 40m + 48m⟹120−80=−40m+48m

⟹40 = 8m⟹40=8m

⟹m = \frac{40}{8} = 5⟹m=

8

40

=5

CHECK:-

⟹40 - 16(3(5) - 5) = - 10(4(5) - 8)⟹40−16(3(5)−5)=−10(4(5)−8)

⟹40 - 16(15 - 5) = - 10(20 - 8)⟹40−16(15−5)=−10(20−8)

⟹40 - 16(10) = - 10(12)⟹40−16(10)=−10(12)

⟹40 - 160 = - 120⟹40−160=−120

⟹ - 120 = - 120⟹−120=−120

therefore,L.H.S=R.H.S
