Step-by-step explanation:

e)

(5x - 1) / 3 - (2x - 2) / 3 = 1

((5x - 1) - (2x - 2)) / 3 = 1

5x - 1 - 2x + 2 = 3

3x + 1 = 3

3x = 3 - 1

3x = 2

x = 2/3

f)

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

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

12x - 4 + 3x + 5 = 18/3

15x + 1 = 6

15x = 5

x = 5/15

x = 1/3

g)

m - (m - 1)/2 = 1 - ( m - 2)/3

(2m - (m - 1))/2 = (3 - (m - 2))/3

cross multiply

3(2m - m + 1) = 2( 3 - m + 2)

6m - 3m + 3 = 6 - 2m + 4

3m + 3 = 10 - 2m

3m + 2m = 10 - 3

5m = 7

m = 7/5 = 1(2/5)

h)

0.6x + (4/5) = 0.28x + 1.16

(5(0.6x) + 4 )/5 = 0.28x + 1.16

3x + 4 = 5( 0.28x + 1.16)

3x + 4 = 1.4x + 5.8

3x - 1.4x = 5.8 - 4

1.6x = 1.8

x = 1.8/1.6

x = 1.125
