aa-b 3x-4 1+x -9 3-2t-p -6-y

a) a+(a-b)= a+a-b=2a -b b) 2x-(-x+4)=2x+x-4=3x-4 c) 7-(-x+6)=7+x-6=x+1 d) -(x+4)+(x-5)=-x-4+x-5=-9 e) 1-(t+p)-(t-2)=1-t-p-t+2=-p-2t+3 f)-(-y+2)+(-2y-4)=y-2-2y-4=-y-6 proszę!!! ;))

a) a+(a-b)= a+a-b = 2a-b b) 2x-(-x+4)= 2x+x-4 = 3x-4 c) 7-(-x+6)= 7+x-6 = 1+x d) -(x+4)+(x-5)= -x-4+x-5 = -9 e) 1-(t+p)-(t-2)= 1-t-p-t+2 = 3-2t-p f)-(-y+2)+(-2y-4)= y-2-2y-4 = -y-6
