Oblicz:
1) (2a - 3b +4) + (-4a + b - 2) - (a - b + 1)
2) - (4x - 2y + 7) - (x=4y - 2) + (5x + y - 4)
3) (6a do potęgi 2 - a -2) - (2a do potęgi 2 - a) + (4a-2) + (a do potęgi 2 - 1)
Bardzo proszę o szybkie rozwiązanie :)

1) (2a - 3b +4) + (-4a + b - 2) - (a - b + 1)=2a-3b+4-4a+b-2-a+b-1=-3a-b+1
2) - (4x - 2y + 7) - (x=4y - 2) + (5x + y - 4)=-4x+2y-7-x-4y+2+5x+y-4=-y-9
3) (6a²- a -2) - (2a²- a) + (4a-2) + (a² - 1)=6a²-a-2-2a²+a+4a-2+a²-1=5a²+4a-5
1.
2a - 3b + 4 - 4a + b - 2- a + b - 1 = -3a - b + 1
2.
-4x + 2y - 7 - x + 4y + 2 + 5x + y - 4 = 7y - 9
3.
6a^2 - a - 2 - 2a^2 + a + 4a - 2 + a^2 - 1 = 5a^2 + 4a - 5
