Answer 1

72/80 - (x - 12/80) = 15/80

72/80 - x + 12/80 = 15/80

- x = 15/80 - 72/80 - 12/80

- x = -69/80

x = 69/80

x + 7/50 = 3/50 + 27/50

x = 3/50 + 27/50 - 7/50

x = 23/50

116/125 - (41/125 + x) = 24/125

116/125 - 41/125 - x = 24/125

- x = 24/125 - 116/125 + 41/125

- x = - 51/125

x = 51/125

4/40 + y + 16/40 = 31/40 + 6/40

y = 31/40 + 6/40 - 4/40 - 16/40

y = 17/40
