Oblicz:
(-2a+3b)-(-3a-b)=
(-2x+y)-(4y-2x)=
(5a+2b)-(-3a+b)=
(-7x-2y)-(-x+3y)=
(5a-3b)-(-2b+2a)=
(-4x-2y)-(-5x-2y)=
Jak ktoś napiszę dodam do znajomych :*

1.(-2a+3b)-(-3a-b)=-2a+3b+3a+b=a+4b
2.(-2x+y)-(4y-2x)=-2x+y-4y+2x=-3y
3.(5a+2b)-(-3a+b)=5a+2b+3a-b=8a+b
4.(-7x-2y)-(-x+3y)=-7x-2y+x-3y=-6x-5y
5.(5a-3b)-(-2b+2a)=5a-3b+2b-2a=3a-b
6.(-4x-2y)-(-5x-2y)=-4x-2y+5x+2y=x
(-2a+3b)-(-3a-b)=-2a+3b+3a+b=a+4b
(-2x+y)-(4y-2x)=-2x+y-4y+2x=-3y
(5a+2b)-(-3a+b)=5a+2b+3a-b=8a+b
(-7x-2y)-(-x+3y)=-7x-2y+x-3y=-6x-5y
(5a-3b)-(-2b+2a)=5a-3b+2b-2a=3a-b
(-4x-2y)-(-5x-2y)=-4x-2y+5x+2y=x
Proszę o naj!!!!
