In the equation below, w, x, y, and z are positive. which of these are equal to Z?

X is equal to z

Step-by-step explanation:

Equation: w/x = y/z

since x and z are both the denometers in this equation, and these two fractions equal each other, then both denometers would have to be the same.

z = wy/x

Step-by-step explanation:

w/x = y/z

Multiply each side by z

w/x *z = y/z *z

w/x *z = y

Multiply by x/w

 x/w *w/x *z = y * w/x

z = wy/x
