Answer:
will make the equation true
Step-by-step explanation:
Given


Required
Which is true for x
We have:

Collect like terms


Solve for x


To factor the trinomial, you can use the ac method where you multiply the first and last terms together (6 and 9) and add up to 15.
In this case ac= 54
2 numbers that multiply to 54 and add up to 15 would be 6 and 9 so place these numbers where the 15 would be:

Then group terms to simplify:

Simplify any like terms:

And group together again:

You can simplify a 3 out of the first expression one more time to get:

Which would be the factored form. I hope this helps :)
6/24 would be equal to 1/4
The second answer which is b the answer is 10 all you do is combine like terms then plug it in and do the next step ill reply when i get the second one
