Question

(3x+2y+z)-(2x+y-z)-(4x-3y-3z)

Answer 1

3x +2y + z -2x –y +z -4x+3y+3z=

3x -2x -4x +2y –y +3y +z+z+3z=

-3x +4y+5z=

Answer 2

(3x+2y+z)-(2x+y-z)-(4x-3y-3z)
3x+2y+z+(−(2x)−(y)−(−z))−(4x−3y−3z)
3x+2y+z+(−2x−(y)−(−z))−(4x−3y−3z)
3x+2y+z+(−2x−y−(−z))−(4x−3y−3z)
3x+2y+z+(−2x−y+1z)−(4x−3y−3z)
3x+2y+z+(−2x−y+z)−(4x−3y−3z)
3x+2y+z+(−2x−y+z)+(−(4x)−(−3y)−(−3z))
3x+2y+z+(−2x−y+z)+(−4x−(−3y)−(−3z))
3x+2y+z+(−2x−y+z)+(−4x+3y−(−3z))
3x+2y+z+(−2x−y+z)+(−4x+3y+3z)
3x+2y+z−2x−y+z−4x+3y+3z
x+2y+z−y+z−4x+3y+3z
−3x+2y+z−y+z+3y+3z
−3x+y+z+z+3y+3z
−3x+4y+z+z+3z
−3x+4y+2z+3z
−3x+4y+5z
