Witam,chciałbym abyście obliczyli zadania(trzeba wyliczyć x)
-3x+6=12+x
4x-8=21+2y
3x+6=-
x-12=2*(x+1)
3x+2,5=7,5
6,5x+2,333=6,5
2,5x+3=6,2
3,5x =2,333=0

1)-3x+6=12+x
-4x=6
x=-1,5
2)4x-8=21+2y y=x??
2x=29
x=14,5
3)3x+6=- ??
4)x-12=2*(x+1)
x-12=2x+2
-x=14
x=-14
5)3x+2,5=7,5
3x=5
x=5/3
6)6,5x+2,333=6,5
6,5x=4,167
x~0,64
7)2,5x+3=6,2
2,5x=3,2
x=1,28
8)3,5x =2,333=0 = to +??
3,5x=-2,333
x~-0,67
