She worked 30 hours per week.

The problem turns out to be the following:
2x+15=3x-15.
First you need to have only one x variable so you subtract the X's:
3x-2x=X
The problem now turns into 15=x-15.
You have to isolate the X so you do x+15. You have to do the same to the other side so 15+15=30, therefore x=30

Solve and check: 5 - 6 = -3<br> k

xxTIMURxx [149]

$5 - 6 = - 3k \\ - 1 = - 3k \\ \frac{1}{3} = k$
First, we combine the terms on the left side of the equation to simplify the equation. Then we divide both sides by -3. k then equals 1/3.
To check, we plug in our value for k into the original equation:
$5 - 6 = - 3k \\ 5 - 6 = - 3( \frac{1}{3} ) \\ - 1 = - 1$
We found k to be 1/3, so for every instance of k, we plug in 1/3. To simplify, we combine the left side to get -1, and we combine the right side to get -1.
Since -1 = -1, our solution is correct.
