roprowadź do najprostszej postaci

-(2-5x)+(1-4x)-x

(a-b)+(3a+2b)-(4a-3b)

-(3x+4y)-(2x-3y)+(-y+4x)

(ax^{2}+ax-a-x)-(2ax-3ax^{2}+a-x)+(2a-ax^{2})

usun nawiasy i zredukuj wyrazy podobne

4a+1-{2a-{(3a-1)-(2-a)+4-3a]+5}-2

-[-(x+3)-(4-x)+2]-(-5+2x)-[-1-(-2x+2)+(x-3)]

-[(2x^{2}-3xy-y^{2})-(-x^{2}+xy-2y^{2})+4xy]-(-3x^{2}+2y^{2})

proszę o dokładne przeliczenia
