Answer 1

A+(a-b) = 2a-b
2x-(x+4 ) = x - 4
7-(-x+6) = 1 + x
-(x+4)+(x-5) = -1
1-(t+p)-(t-2) = 3 - 2t - p
-(y+2)+(-2y-4) = -3y - 6

Answer 2

a)a+(a-b)=a+a-b=2a-b
b)2x-(x+4)=2x-x-4=x-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=3-2t-p
f) -(-y+2)+(-2y-4)=y-2-2y-4=-y-6
