If you want to check your answer to solving an equation, just plug the value of x you got into the initial equation.

#

So does 2/9 * 6/9 = 1/3?

Does 4/3 * 20/3 = 1/5? (Correcting your multiplication error)

Uhhmm

Now, I can see that you cross-multiplied. Cross-multiplying is actually multiple steps done at one time, so it may be illuminating to see them done explicitly: 4x/3 = 1/5 4x/3 * 3 = 1/5 * 3 4x * 3/3 = 3/5 4x * 1 = 3/5 4x = 3/5 4x * 5 = 3/5 * 5 20x = 3 * 5/5 20x = 3 * 1 20x = 3

If any step here is confusing to you, I'll be happy to explain.
