Zad: Zredukuj wyrazy poobne a) (y+4)-(2y-3x+1)= b) -3*(2x-y+5)= c) (-2x+y)+(3x-4y)= d) (m-2)-(4m+5n-7)= e) 4(-2x-y+5)= f) -2(x-y)-3(x+1)-(y-4)

a) (y+4)-(2y-3x+1)= y + 4 - 2y + 3x - 1 = 3 - y + 3x b) -3*(2x-y+5)= -6x + 3y - 15 c) (-2x+y)+(3x-4y)= -2x + y + 3x - 4y = x - 3y d) (m-2)-(4m+5n-7)= m - 2 - 4m - 5n + 7 = 5 - 3m - 5n e) 4(-2x-y+5)= - 8x - 4y + 10 f) -2(x-y)-3(x+1)-(y-4) = -2x + 2y - 3x - 3 - y + 4 = -5x + y + 1

a)*(y+4)-(2y-3x+1)=y+3+3x b =2*2x-y c =x-3y d =-3m-5-5n e =9-2x-y f =-1+2x+2y
