2 + 14z = -8 + 9zSubtract 9z from each side:2 + 5z = -8Subtract 2 from each side:5z = -10Divide each side by 5:z = -2
It is a linear equation in the variable z.
(z=-3) and (z=7)
0
x + y + z = 0 x = a - b, y = b - c, z = c - a, therefore a - b + b - c + c - a = ? a - a + b - b + c - c = 0

z = -4 x-5 y+2

(2+x+y+6+z) += 9x,y and z are variables, there are 3.
If th equestion meant: (x+y+z)^2The expansion is:(x+y+z)^2= x^2+2xy+y^2+2yz+z^2+2zx
2+3 = 5 * 2 = 10. 7+2 = 9 * 7 = 63.6+5 = 11 * 6 = 66.x+y = z * x = n.9+7 = 16 * 9 = 144
