$⟹40 - 16(3m - 5) = - 10(4m - 8)$

$⟹40 - 48m + 80 = - 40m + 80$

$⟹40 + 80 - 48m = - 40m + 80$

$⟹120 - 48m = - 40m + 80$

$⟹120 - 80 = - 40m + 48m$

$⟹40 = 8m$

$⟹m = \frac{40}{8} = 5$

CHECK:-

$⟹40 - 16(3(5) - 5) = - 10(4(5) - 8)$

$⟹40 - 16(15 - 5) = - 10(20 - 8)$

$⟹40 - 16(10) = - 10(12)$

$⟹40 - 160 = - 120$

$⟹ - 120 = - 120$

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

Answer:

$[tex]40 - 16(3m - 5) = - 10(4m - 8)$[/tex]

40-48m-80= -40m +80

-40-48m= -40m +80

8m +120= 0

m=- 120/8

m= -15
