VA rog cat se poate de repede

Answer 1

5y-3=-18
5y=-18+3
5y=-15
y=-15:5
y=-3

-14x=266
14x=-266
x=-266:14
x=-19

1-2x=3
-2x=3-1
-2x=2
2x=-2
x=-2:2
x=-1

17=1-3x
-3x=17-1
-3x=16
3x=-16
x=-16/3 /=supra

2(x-1)=4
2x-2=4
2x=2+4
2x=6
x=6:2
x=3

(-4)(-x)+(-7)=9
4x-7=9
4x=7+9
4x=16
x=16:4
x=4

3x+1-x=5
2x+1=5
2x=5-1
2x=4
x=4:2
x=2

4x+5-x=15
3x+5=15
3x=15-5
3x=10
x=10/3
