4(3x-2)+5(4x-3)
-2(5-3y)+4(3-2y)
-4(-x+5y)+2(3x-y)
a-(y+a)-(y-a)
-(7y-5)-(6y-4)
-10(7x-1)+5(6-4x)
3(2k-4p)-(-6k+p)
-2(5-3y)+4(3-2y)

Answer 1

-k+3-(-x-k+3)=-k+3+x+k-3=x
8a-(x-5a)+(-4a+x)=8a-x+5a-4a+x=9a
4(3x-2)+5(4x-3)=12x-8+20x-15=32x-23
-2(5-3y)+4(3-2y)=-10+6y+12-8y=-2y+2
-4(-x+5y)+2(3x-y)=4x-20y+6x-2y=10x-22y
a-(y+a)-(y-a)=a-y-a-y+a=a-2y
-(7y-5)-(6y-4)=-7y+5-6y+4=-13y+9
-10(7x-1)+5(6-4x)=-70x+10+30-20x=-90x+40
3(2k-4p)-(-6k+p)=6k-12p+6k-p=12k-13p
-2(5-3y)+4(3-2y)=-10+6y+12-8y=-2y+2
