[" (1) If "x^(2)+y^(2)+z^(2)=2(x+y-1)],[" Find the value of "x^(3)+y^(3)+z^(3)]

If x^(2)+y^(2)+z^(2)=2(x-y-z)-3 Find the value of 2x-3y+4z

If x = 2a- 1, y = (2a - 2) and z =3 - 4a, then the value of x ^(3) + y ^(3) + z ^(3) will be :

If x = 2, y = 3 and z = -1, find the values of : x-:y

If x = 1, y = 2 , z = 5 , find the value of x^3 - y^3 -z^3

If x + y + z = 12, x^(2) + Y^(2) + z^(2) = 96 and (1)/(x)+(1)/(y)+(1)/(z)= 36 . Then find the value x^(3) + y^(3)+z^(3).

If x + y + z = 12, x^(2) + Y^(2) + z^(2) = 96 and (1)/(x)+(1)/(y)+(1)/(z)= 36 . Then find the value x^(3) + y^(3)+z^(3).

If x = 2, y = 3 and z = -1, find the values of : (2x-3y+4z)/(3x-z)
