### Difficult Problems

1

Solved example of rational equations

$\frac{2}{x+1}=\frac{3}{x-1}$
2

Inverting the inequation

$\frac{x+1}{2}=\frac{x-1}{3}$
3

Multiply both sides of the equation by $2$

$x+1=2\left(\frac{x-1}{3}\right)$
4

Simplify the fraction $2\left(\frac{x-1}{3}\right)$

$x+1=\frac{2}{3}\left(x-1\right)$
5

Solve the product $\frac{2}{3}\left(x-1\right)$

$x+1=\frac{2}{3}x-\frac{2}{3}$
6

We need to isolate the dependent variable $x$, we can do that by subtracting $1$ from both sides of the equation

$x=-\frac{5}{3}+\frac{2}{3}x$
7

Rearrange the equation

$-\frac{5}{3}+\frac{2}{3}x=x$
8

We need to isolate the dependent variable $x$, we can do that by subtracting $-\frac{5}{3}$ from both sides of the equation

$\frac{2}{3}x=x+\frac{5}{3}$
9

Grouping terms

$-\frac{1}{3}x=\frac{5}{3}$
10

Eliminate the $-\frac{1}{3}$ from the left, multiplying both sides of the equation by 

$x=-5$

$x=-5$
