Step-by-step explanation:
1. => (3m-5)/2 + 1/2(4m-8) = 2m
=> (3m-5)/2 + 1/2×4m - 1/2×8 = 2m
=> (3m-5)/2 + 2m - 4 = 2m
=> 3m - 5 + 2m - 4 = 2(2m)
=> 5m -9 = 4m
=> -9 = 4m -5m
=> -9 = -m
=> 9 = m
2. y + 7 = (3y - 5)/9 + 1
=> 9(y + 7) = 3y - 5 + 1
=> 9y + 63 = 3y - 4
=> 9y - 3y = - 4 - 63
=> 6y = - 67
=> y = -67/6
I hope this answer is helpful for you ....
