Step-by-step explanation:

( i )

4 ( m + 3 ) = 18

4m + 12 = 18

4m = 18 - 12

m = 6 / 4

m = 1.5

( ii )

- 2 ( x + 3 ) = 5

- 2x - 6 = 5

-2x = 5 + 6

x = 11 / - 2

x = - 5.5

( iii )

3 ( n - 5 ) = - 21

3n - 15 = - 21

3n = - 21 + 15

n = - 7 / 3

( iv )

4 ( 2 - x ) = 9

8 - 4x = 9

- 4x = 9 - 8

x = 1 / - 4

x = - 0.25

( vii )

8 ( 2 - a ) = - 5a

16 - 8a = - 5a

16 = - 5a + 8a

a = 16 / - 3

a = - 16 / 3
