I have come across a math problem that I can't solve. The equation is: y/4z = x/w (Solve for: z)

y/4z = x/w
multiply both sides by 4z
4z * (y/4z) = 4z * (x/w)
cancel 4z on left top and bottom
y = 4z * (x/w)
multiply both sides by w/x
y * w/x = 4z * (x/w) * w/x
cancel xw/wx on right
wy/x = 4z
divide both sides by 4
z = (wy)/(4x)
note. z cannot equal 0 because then y/4z = infinity

Start by just inverting both sides of the equation. You can prove that this does not effect the equality by doing an example of a simple problem such as:
1/4 = 1/4, inverted to:
4 = 4 shows that this does not change the equality, and should make it easier for you to solve the equation.

z=yw/4x
Just move things around one at a time.

z = wy/4x
