-х-2+3(х-3)=3(4-х)-3
-х-2+3х-9=12-3х-3
-х+3х+3х=12-3+2+9
5 х=20
х=20:5
х=4
-х-2+3х-9=12-3х-3
-х+3х+3х=12-3+2+9
5 х=20
х=20:5
х=4
-Х-2+3(Х-3) = 3(4-Х)-3
-Х-2+3Х-9 = 12-3х-3
-Х-2+3Х-9-12+3Х+3 =0
5Х-20 =0
5Х = 20
Х = 20:5
Х = 4
-4-2+3(4-3) = 3(4-4)-3
-3=-3
-Х-2+3Х-9 = 12-3х-3
-Х-2+3Х-9-12+3Х+3 =0
5Х-20 =0
5Х = 20
Х = 20:5
Х = 4
-4-2+3(4-3) = 3(4-4)-3
-3=-3
