══════════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
