Question

2+8x=3x+9
6-2x=3x-10
5-2x=8x+9
3-4x=4x-5
4x+4=-6x-5

Answer 1

1) 8х-3х=9-2
5х=7
х=1,4

2) -2х+3х=-10-6
Х=-16

3) -2х-8х=9+5
-10х=14
х=-1,4

4) -4х-4х=-5-3
-8х=-8
х=1

5) 4х+6х=-5-4
10х=-9
х=-0,9

Answer 2

2+8x=3x+9; 8х-3х=9-2; х=7/5; х=1,4////// 6-2x=3x-10; -2х-3х=-10-6; -5х=-16; Х=16/5; х=3 1/5;///// 5-2x=8x+9; -2х-8х=9-5; -10х=4; х=-2/5;///// 3-4x=4x-5; -4х-4х=-5-3; -8х=-8; х=8/8; х=1;///// 4x+4=-6x-5; 4х+6х=-5-4; 10х=-9; х=-0,9
