The value of 7m−3 is half as big as the value of 12m+1

m = 3

Step-by-step explanation:

the value of 7m−3 is half as big as the value of 12m+1 implies that

7m - 3 = ( 12m + 1)

cross multiplying, we have

2(7m-3) = 12m + 1

Expanding the L.H.S , we have

14m - 6 = 12m + 1

collecting the like terms ,we have

14m - 12m = 1 + 6

2m = 7

Dividing through by 2

m = 7/2

m = 3
