Hii Mates,...

1. y - 6/4 + y - 3/5 =5y - 4/8

5(y - 6/4) + 4(y - 3/5) = 5y - 4/8

5y - 30 + 4y - 12/20 = 5y - 4/8

9y - 42 = 5y - 4/8

Cross multiplication,

8(9y - 42) = 20(5y - 4)

72y - 336 = 100y - 80

100y - 72y = 336 - 80

28y = 256

y = 256/28

y = 9.15

2. m - (m - 1)/2 = 1- (m - 2)/3

(2m - m + 1)/2 = (3 - m + 2)/3

(m + 1)/2 = ( 5 - m)/3

3(m + 1) = 2(5 - m)

3m + 3 = 10 - 2m

3m + 2m = 10 - 3

5m = 7

m = 7/5
