Answer 1

a) 6x - 3 = 2x +9

6x - 2x = 9 +3

4x = 12

x= 12/4

x= 3

b) 4x - 1 = - 3x +3

4x +3x = 3 + 1

7x = 4

x= 4/7

c) 6x + 9 - 4x +4= 3

2x+13 = 3

2x = 3 - 13

2x = - 10

x= -10/2

x= - 5

d) 7x - 7 - 2x +10 = x - 5

5x +3 = x -5

5x - x = - 5 -3

4x = - 8

x = - 8/4

x= -2

e) 5x +3x +6 = 15

8x = 15 -6

8x = 9

x = 9/8
