musze to zapisac krócej
2.
to trzeba napisać w prostrzej postaci
2x-5x+7-x
2a+b-4b
x-2x+3+x-4
3x-y+4x-2y
2x-6+4x+2
3y-5-5y-6
-2a+2b-3a-3b
1/2t-2x+3t-x-t
dzięki wszytskim :)

Answer 1

1.-17x-15x-13x-10x+10x+13x+15x+17x=0
-10x-8x-6x-2x+2x+4x+6x+8x=-6x
-123x+55x-39x+23x-155x+239x=0
439x-427x+369x-357x+229x-217x=36x
2.
2x-5x+7-x=-4x+7
2a+b-4b=2a-3b
x-2x+3+x-4=-1
3x-y+4x-2y=7x-3y
2x-6+4x+2=6x-4
3y-5-5y-6=-2y-11
-2a+2b-3a-3b-5a-b
1/2t-2x+3t-x-t=2 1/2t-3x

Answer 2

-17x-15x-13x-10x+10x+13x+15x+17x=0
-10x-8x-6x-2x+2x+4x+6x+8x=-6x
-123x+55x-39x+23x-155x+239x=0
439x-427x+369x-357x+229x-217x=36x

2x-5x+7-x=-3x+7
2a+b-4b=2a-3b
x-2x+3+x-4=-1
3x-y+4x-2y=7x-3y
2x-6+4x+2=6x-4
3y-5-5y-6=-11-2y
-2a+2b-3a-3b=-5a-b
1/2t-2x+3t-x-t=2,5t-3x

Answer 3

-17x-15x-13x-10x+10x+13x+15x+17x = 0
-10x-8x-6x-2x+2x+4x+6x+8x = -6x
-123x+55x-39x+23x-155x+239x = 0
439x-427x+369x-357x+229x-217x = 36x

2.
2x-5x+7-x = -4x + 7
2a+b-4b = 2a - 3b
x-2x+3+x-4 = -1
3x-y+4x-2y = 7x - 3y
2x-6+4x+2 = 6x - 4
3y-5-5y-6 = -2y - 11
-2a+2b-3a-3b = -5a - b
1/2t-2x+3t-x-t = 2½t - 3x
