Question

Q:-solve and find the value of m and hence verify
$40 - 16(3m - 5) = - 10(4m - 8)$
​

Answer 1

Answer:

⟹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 = 40/8 = 5

Answer 2

Step-by-step explanation:

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

$24(3m - 5) = - 40m + 80$

$72m - 120 = - 40m + 80 \\ = 72m + 40m = 80 + 120 \\ = 112m = 200 \\ m = \frac{112}{200} = \frac{56}{100} = \frac{28}{50} = \frac{14}{25}$
