A) X + 3 / 5 = 4

X = 4 - 3 / 5

4 - 3 / 5 = [(4x5) - 3] / 20 = (20 - 3) / 20 = 17 / 3

X = 17 / 3

b) 3X + 5X + 36 = 100

8X = 100 - 36

8X = 64

X = 64 / 8

X = 8

c) (2 / 5)X + (3 / 10)X = 40

(2 / 5)X + (3 / 10)X = (2(2) + 3) / 10X = (4 + 3) / 10X = (7 / 10)X

(7 / 10)X = 40

7X = 400

X = 400 / 7

d) 2(X + 3) = 10

2X + 6 = 10

2X = 10 - 6

2X = 4

X = 4 / 2

X = 2

e) 6(X - 2) = 18

6X - 12 = 18

6X = 18 + 12

6X = 30

X = 30 / 6

X = 5.
