-3x=1,5 6x-9=2x+3 X+2 (3x-2)=10

Question

-3x=1,5
6x-9=2x+3
X+2 (3x-2)=10

Answer 1

-3х=1,5;
-х=1,5:3;
-х=0,5;
х=-0,5.

6х-9=2х+3;
6х-2х=9+3;
4х=12;
х=12:4;
х=3.

х+2(3х-2)=10;
х+6х-4=10;
7х-4=10;
7х=10+4;
7х=14;
х=14:7;
х=2.

Answer 2

-3х = 1,5
3х = -1,5
х = -0,5
2) 6х-9 = 2х + 3
6х - 9 - 2х - 3 = 0
4х - 12 = 0
4х = 12
х = 3
3) х + 2(3х-2) = 10
х + 6х - 4 = 10
7х - 4 = 10
7х = 10+4
7х = 14
х = 2
