решительно уравнение ! ​

1) -6х-5=4х; -6х-4х=5; -10х=5; х=5:(-10); х= -0,5

2) -7x + 8 = 9x; -7x - 9x = -8; -16x = -8;x = -8/(-16); x = 0,5

3) -9х - 8 = -8х;-8=9х-6х;  х=8

4) -9х - 8 = -8х;-8=9х-6х;  х=8

5) -5x + 2 = -10x; -5x + 10x = -2; 5x = -2; x = -2/5

6) -5х+2=-10х; -5х+10х=-9; 5х=-9; х=-9/5; х=-1.8

7) -1 + 2x = 10x + 3; -2x + 10x = -(3 + 1); 8x = -4; х=-4/8; x = -0.5

8) 9 + 4x = 8x - 9; 4x - 8x = -9 - 9;-4x = -18; х=-18/(-4); x = 4.5

9) 6-2х=3х-10; 5х=16; х=16/5; х=3.2
