Question

16. 3(x-1)=2(2-x)+6
17. 4(3-h)-11=2,7m+3,2
18 . -3(3y+4)+4(2y-1)=0
19. 0,3(5x-7)=3(0,2x+3,2)

Answer 1

1)3х-3=4-2х+6
3х+2х=4+6+3
5х=13
х=13/5
х=2,6
3)-9y-12+8y-4=0
-9y+8y=4+12
-y=16
y=-16
4)1.5x-2.1=0.6x+9.6
0.9x=11.7
x=11.7/0.9
x=13

Answer 2

1)3х-3=4-2х+6 3х+2х=4+6+3 5х=13 х=13/5 х=2,6 3)-9y-12+8y-4=0 -9y+8y=4+12 -y=16 y=-16 4)1.5x-2.1=0.6x+9.6 0.9x=11.7 x=11.7/0.9 x=13
