Question

- 2 (х + 3) – (- х – 2) = 3 (-х + 4) + 3(х – 5)

Answer 1

-2х-6+х+2=-3х+12+3х-15
-х-4= -3
-х=1
х=-1

Answer 2

1,2 -2,6х-2-5,6х=-27,04

Answer 3

-8,2х= -27,04+2-1,2

Answer 4

-8,2х= -26,24

Answer 5

х=3,2

Answer 6

1)5,2 + 0,5 (х – 3) = 3 – 0,8 (х + 4)
2)0,3 (5х + 0,2) = -2,6 – (2,7х – 1,4)
