P = m+n/q
by timesing by p then dividing by q
<u>Answer:</u>
x = 4, it is an extraneous solution.
<u>Step-by-step explanation:</u>
Translating the given statement, we get the following equation:

Dividing both sides by 3, we get:

Now we will take square on both sides of the equation to get rid of the square root to get:

So we are left with:

Therefore, the solution is 4.
Also, it is an extraneous solution because the equality is not met by substituting x = 4 in the original equation:




She can use them by putting them next to each other and seeing the difference between each one.
