X = yz
How do you solve for z?

Answer. z=x/y. Isolate “z” by dividing “y” from both sides.
Explanation. Treat the variables like any other number(s). We can plug in numbers but you don’t have to. We must isolate z to get the answer. To do this, divide both sides by y and you get your answer of z=x/y. Hope this helps, let me know if it’s correct so others can use it :)
Good luck.
