Răspuns:

-5x+2= -4x+1

-5x+4x= 1-2

-1x= -1

x= -1 supra -1

x= 1

5x+17= 3x-31

5x-3x= -31-17

2x= -48

x= -48 supra 2

x= -24

3x-9+x= 2x-27

3x+x-2x= -27+9

2x= -18

2x= -18 supra 2

x= -9

8x-5x+32= 2x-51

8x-5x-2x= -51-32

1x= -83

x= -83

5x+13-2x= 9x+22-5x

5x-2x-9x+5x= 22-13

-1x= 9

x= -9
