Question

Solve for x: z = xy
x =
x =
x = yz
y = xz

Answer 1

z = xy

Divide both side by 'y'

x=z/y

Answer 2

It seems that not all your answer choices are complete. But I will show you how anyways.

You know that it z = x times y, well if you can do inverse operations you can get x if you divide y to both sides.
\[x=z \div y\]
