Answer 1

3)4 x-8-2x = x - 2

4x - 2x - x = - 2 + 8

2x - x = 6

x= 6

4) 10 x - 8 - 2 = 7 x-4

10x - 7x = - 4 + 8 + 2

3x = 4 + 2

3x = 6

x=6/3

x= 2

5) 2 x +5 -5x = -1

2x - 5x = - 1 - 5

- 3x = - 6

x= - 6/-3

x= 2

6) 4 x - 4 - 5 x = -6 + 90

4x - 5x = - 6 + 90 + 4

- x = 84 + 4

- x = 88 (-1)

x= - 88

7) – 3 x + 10 = 2 x + 8 + 1

- 3x - 2x = 8 + 1 - 10

- 5x = 9 - 10

- 5x = - 1(-1)

5x = 1

x= 1/5

8) 3 x - 4 = 11

3x = 11 + 4

3x = 15

x= 15/3

x= 5

9) 4 x + 6 = 12 - 2x

4x + 2x = 12 - 6

6x = 6

x= 6/6

x= 1

10) - 10 - 8 = 2 x + 4

- 18 = 2x + 4

- 18 - 4 = 2x

- 22 = 2x

x= - 22/2

x= - 11

11) 5 x + 4x - 10 = 2 x-2

5x + 4x - 2x = - 2 + 10

9x - 2x = 8

7x = 8

x= 8/7
