So you have:
\frac{3}{x} + 2  =  \frac{2}{x} - 1


1) Start off by multiplying both sides by x to simplify the problem:
\frac{3}{x} + 2 = \frac{2}{x} - 1 \\
x(\frac{3}{x} + 2) = (\frac{2}{x} - 1)x\\
3 + 2x = 2 - x


2) Now isolate the x by moving all terms with x onto one side and all other terms onto the other side:
3 + 2x = 2 - x\\
3x = -1

3) Finally, divide by 3 on both sides to find the value of x:
3x = -1\\
x =  \frac{-1}{3}

------

Answer: x = \frac{-1}{3}

On an exam, Mafuyu scored in the 20th percentile. If there were 50 students in the class, how many students scored lower than he
Reptile [31]

Using the percentile concept, it is found that 10 students scored lower than he did.

<h3>What is the meaning of the percentile of a measure?</h3>

When a measure is in the xth percentile of a data-set, it is greater than x% of the measures and lesser than (100 - x)%.

In this problem, he scored on the 20th percentile, that is, higher than 20% of the 50 students. Then:

0.2 x 50 = 10.

10 students scored lower than he did.
