As an example, let's look at B: x=1, y=2, z=0. Evaluating the left side of the given expression in x, y and z, we get x + 2y - z = 8 => 1 + 2(2) - 0 = 5, which does not equal 8. So B is not a solution. Please check out the other possible solutions. Which set {x, y, z} makes the given equation true?
