Answer 1

Oi....

i) x - (x + 1) = 12 - (3x - 2)

x - x - 1 = 12 - 3x + 2

x - x + 3x = 12 + 2 + 1

3x = 15

x = 15/3

x = 5

l) - 10 + 4 - 2x = - 4x - 7

- 2x + 4x = - 7 - 4 + 10

2x = - 1

x = - 1/2

o) x + 4(x - 1) = 9 - 2(x + 3)

x + 4x - 4 = 9 - 2x - 6

x + 4x + 2x = 9  - 6 + 4

7x = 7

x = 7/7

x = 1

p) 5(3x - 2) = 2(6x + 3)

15x - 10 = 12x + 6

15x - 12x = 6 + 10

3x = 16

x = 16/3

q) 2(3x - 1) + 2(3 - x) = 0

6x - 2 + 6 - 2x = 0

3x = - 6 + 2

3x = - 4

x = - 4/3

r) 7(x - 1) = 2(3x + 1)

7x - 7 = 6x + 2

7x - 6x = 2 + 7

x = 9
