Question

Need help idk how to slove this

Answer 1

Multiply both sides of this equation by Z.

This will eliminate the denominator on the left because Z over Z on the left cancels out. And now we have 3z on the right side.

x + y = 3z

Since we are to solve for y, we want to move x to the left by subtracting it from both sides.

y= 3z - x

This is as simplified as we can make it.

Answer 2

Hi!

I'm not sure how to slove this, but I do know how to solve it ;D

We can't know the exact value of y, but we can isolate y on one side. First, multiply by z on both sides.

`(x+y)/(z*z)=3*z`

x + y = 3 * z

Now subtract x from both sides.

x - x + y = 3 * z - x

y = 3 * z - x

The answer is y = 3 * z - x

Hope this helps! :)
