### Transcript

We just combine terms to simplify and we're there...

...wherever there is....but okay we have 3x, 7x which we can add

to get 10x. We can subtract 9 from both sides

35 -9 is 26, so we have 10x equals 26.

Now divide both sides by 10

and X equals 26 over 10. Done.

Wait...not done...there's no 26 over 10 in the answers.

What did we do wrong? Well, we need to reduce.

10 and 26 are even numbers

so if nothing else we can divide 2 into each of them evenly

and getting now reduced 13 over 5 which ta-da

is here. Answer C.
