x = 2y
y = 4z
2z = w
w <> 0
x/w = ?????
x/w = 2y/2z
y = 4z, so we can replace y with 4z to get:
x/w = (2*4z)/2z) = 8z/2z = 4
your answer should be 4.
let's do it again to make sure.
the equation we want is x/w
we know that x = 2y so we substitute 2y for x to get:
2y / w
we know that w = 2z so we substitute 2z for w to get:
2y / 2z
we know that y = 4z, so we substitute 4z for y to get:
2*4z / 2z
the z cancels out and the 2 cancels out and we are left with 4.
that's your answer.
