Question

С ОБЯСНЕНИЕМ
-4х=-10Х-9
6+3Х=4х-1
-1+2х=10Х+5
-4+3Х=8х+15
9+4х=8х-9

Answer 1

-4х=-10х-9
-4х+10х=-9
6х=-9
х=-9:6
х=-1,5

6+3х=4х-1
3х-4х=-1-6
-1х=-7
х=-7:(-1)
х=7

-1+2х=10х+5
2х-10х=5+1
-8х=6
х=6:(-8)
х=-0,75

-4+3х=8х+15
3х-8х=15+4
-5х=19
х=19:(-5)
х=-3,8

9+4х=8х-9
4х-8х=-9-9
-4х=-18
х=-18:(-4)
х=4,5
