Решите уравнение: 1) 2х+17 = 22 + 3х 2) 3,4х-4 = 4,8-х 3) 2х+7=х+5,5 4) 5-3х = 2х-8 5) 9,5х+2 = 5,7х-5,6 6) 1,5х+8 = 3,1х+16 7) 2,9х+7,4 = х+1,7

1) 2х+17 = 22 + 3х
2х-3х=22-17
-х=5
х=-5

2) 3,4х-4 = 4,8-х
3.4х+х=4.8+4
4.4х=8.8
х=8.8:4.4
х=2

3) 2х+7=х+5,5
2х-х=5.5-7
х=-1.5

4) 5-3х = 2х-8
-3х-2х=-8-5
-5х=-13
х=-13:(-5)
х=2.6

5) 9,5х+2 = 5,7х-5,6
9.5х-5.7х=-5.6-2
3.8х=-7.6
х=-7.6:3.8
х=-2

6) 1,5х+8 = 3,1х+16
1.5х-3.1х=16-8
-1.6х=8
х=8:(-1.6)
х=-5

7) 2,9х+7,4 = х+1,7
2.9х-х=1.7-7.4
1.9х=-5.7
х=-5.7:(1.9)
х=-3
