Given:
.

.
When you multiply both sides by 3 you get:
.

.
On the left side the 3 in the numerator cancels with the 3 in the denominator to give:
.

.
On the left side you are left with just -x and on the right side the 3 times the 3 is 9.
This makes the equation:
.

.
But you want to solve for +x, so just multiply both sides by -1 and you have:
.

.
Check the answer by returning to the original equation you were given and substitute into
that equation -9 for x. So start with:
.

.
When you replace x with -9 it becomes:
.

.
The two minus signs in the numerator on the right side combine to be a + sign and the
equation is then:
.

.
And when you divide out the left side the result is:
.

.
which is true. Therefore, x = -9 is the correct answer.
.
Hope this helps you to find your mistake.
