how do you simplify this with algebraic expression please help me

Piece of cake. Just Combine like terms!

2x-2y+5z-2x-y+3z

Since 2x and -2x are like terms, add -2x to 2x to get 0.

0-2y+5z-y+3z

Since -2y and -y are like terms, subtract y from -2y to get -3y.

-3y+5z+3z

Since 5z and 3z are like terms, add 3z to 5z to get 8z.

-3y+8z

2x-2y+5z-2x-y+3z

collect like terms

5z+3z-2y-y+2x-2x

2x-2x will cancel out

therefore 5z+3z-2y-y=8z-3y

2x – 2y + 5z – 2x – y + 3z

– 2y + 5z – y + 3z (2x-2x=0)

– 2y + 8z – y (3z+5z=8z)

– 3y + 8z (-2y-y)

8z – 3y

group the terms

x(2-2)+y(-2-1)+z(5+3)

x*0+y*-3+z*8

so the expression simplifies to

8z-3y
