-3x-6x= - 10-8

-9x= - 18 //:-9

x=2

b) 5x-3+2x=4x+9

7x-3=4x+9

7x-4x= 9+3

3x= 12 //:3

x= 4

c) 2+4x-1+2x= - 8+4x-7

2x= -14 //:2

x= -7

a) 8 - 3x = 6x - 10

-3x - 6x = -10 - 8

-9x = -18 /:(-9)

x = 2

b) 5x - 3 + 2x = 4x + 9

5x + 2x - 4x = 9 + 3

3x = 12 /:3

x = 4

c) 2 + 4x - 1 + 2x = -8 + 4x - 7

4x + 2x - 4x = -8 - 7 - 2 + 1

2x = -16 /:2

x = -8
