1) x + 7/12 = 3/4
x = 3/4 - 7/12
x = 9/12 - 7/12
x = 2/12
x = 1/6

2) x - 1/6 = 1/9
x = 1/9 + 1/6
x = 2/18 + 3/18
x = 5/18

3) x - 3/5 = 3/8
x = 3/8 + 3/5
x = 15/40 + 24/40
x = 39/40

4) x + 5/24 = 7/12
x = 7/12 - 5/24
x = 14/24 - 5/24
x = 9/24
x = 3/8

5) y + 2/7 = 1/3
y = 1/3 - 2/7
y = 7/21 - 6/21
y = 1/21

6) x - 1/6 = 7/9
x = 7/9 + 1/6
x = 14/18 + 3/18
x = 17/18

7) y - 3/8 = 5/32
y = 5/32 + 3/8
y = 5/32 + 12/32
y = 17/32

8) y + 2/5 = 1/2
y = 1/2 - 2/5
y = 5/10 - 4/10
y = 1/10
