d) (0,1x(do kwadratu) - 3x - 4) + (-0,6x(do kwadratu) + 3x - 4y) =

e) (p(do kwadratu) - 3q + p - 2) + (4q - 2p + p(do kwadratu) - 1) =

f) (4a - 2b + 3) + (2b - 4) + (4b - 2a + 1) =

g) (x - 2y) + (3xy - 2x - 1) + (4y - 2xy + 2) =

Answer 1

c) (m - 5n - 2mn) + (4m - 5mn + 5n) =5m-7mn

d) (0,1x(do kwadratu) - 3x - 4) + (-0,6x(do kwadratu) + 3x - 4y) =-0,5x²-4y-4

e) (p(do kwadratu) - 3q + p - 2) + (4q - 2p + p(do kwadratu) - 1) = 2p²+q-p-3

f) (4a - 2b + 3) + (2b - 4) + (4b - 2a + 1) =2a+4b

g) (x - 2y) + (3xy - 2x - 1) + (4y - 2xy + 2) =-x+2y+xy+1
