a) (a+b) - (2a - b) - (a-2b)
a+b-2a+b-a+2b= -2a+4b
b) (3x - y + 1) - ( x +y ) + (y -x)
3x-y+1-x-y+y-x= x-y+1
c) -( kx + ny ) - (3kx+ 2ny) + (5kx - 3ny)
-kx-ny-3k-2ny+5kx-3ny
b) (3x - y + 1) - ( x +y ) + (y -x)=3x-y+1-x-y+y-x=x-y+1
c) -( kx + ny ) - (3kx+ 2ny) + (5kx - 3ny=)-kx-ny-3kx-2ny+5kx-3ny=kx-6ny
d) (2ab + a + 3) - (3ab - a + 3)=2ab+a+3-3ab+a-3=-ab+2a
e) (4x - 3x) - (x + 0,1x ) - (x - 0,1x)=x-1,1x=-0,1x
b) (3x - y + 1) - ( x +y ) + (y -x)=3x-y+1-x-y+y-x=1+1x-1x
c) -( kx + ny ) - (3kx+ 2ny) + (5kx - 3ny)=-kx-ny-3k-2ny+5kx-3ny=4kx-6ny-3k
d) Niewiem o co ci tu chodziło ;(
e) (4x - 3x) - (x + 0,1x ) - (x - 0,1x)=4x-3x-x-0,1x-x+0,1x=-1x
