Answer 1

A)2x-(3a-2)=2x-3a+2
b)a-(-2a+1)=a+2a-1=3a-1
c)2x-5-(x-3)=2x-5-x+3=x-2
d)(3x-6)-(-2x+4)=3x-6+2x-4=5x-10
e)(3x-2x)-(2x-3)=3-2x-2x+3=-4x+6
f)(x+2y-3)-(2x-3y+1)=x+2y-3-2x+3y-1=-x+5y-4
g)(x²-2x+3)-(2x²+3x-1)=x²-2x+3-2x²-3x+1=-x²-5x+4
h)(3x-2y+5z)-(x-5y-6z)=3x-2y+5z-x+5y+6z=2x+3y+11z
i)(2x-3y)-(-5x+3y)=2x-3y+5x-3y=7x-6y
j)-(2x-3y+4z)-(5x-6y+7z)=-2x+3y-4z-5x+6y-7z=-7x+9y-11z
k)(2x-1)+(3x-2)-(4x-6)=2x-1+3x-2-4x+6=x+3
l)(-y+4)-(2y-1)+(3y+3)=-y+4-2y+1+3y+3=8
m)(4a-5)-(5a+4)+(2a+1)=4a-5-5a-4+2a+1=a-8
n)(x-5)-(2x-1)-(-x+4)=x-5-2x+1+x-4=-8
o) i p) nie widać końca
