Bonjour,

a. 7/9y + 5 = 8

7/9y = 8 - 5

7/9y = 3

y = 3 * 9/7

y = 27/7

b. 1/16x - 2 = 5/8

1/16x = 5/8 + 2

1/16x = 10/16 + 32/16

x = 10 + 32

x = 42

c. 1/4x - 3/8 = 2/3

1/4x = 2/3 + 3/8

6/24x = 16/24 + 9/24

6x = 16 + 9

6x = 25

x = 25/6

d. 3/7y - 5/35 = - 8/14

3/7y = - 8/14 + 5/35

3/7y = - 4/7 + 1/7

3y = - 7 + 1

3y = - 6

y = - 6/3

y = - 2.
