Answer 2

Hi there!

Great question! :D

To figure out our unknown value, we can replace our unknown value, or blank space, with x.

So our equation would look something like
`4x = 30`

We have a variable next to a number to show we are multiplying. But since we're figuring out an unknown, we'll do the opposite, which is division.


`4x = 30`

We'll divide both sides by our 4.


`(4x)/(4) = (30)/(4)`

We can eliminate the variable right away on our left side of our equation. This makes it look like there's not a lot of steps through solving.


`(30)/(4) = 7.5`

Final answer:


`x = 7.5`

When in doubt of your answer, we can multiply 4 by 7.5 and see what we get. We should get 30.


`4 * 7.5 = 30 :)`

We were right!

Hope this helps! :D
