###  Difficult Problems

1

Solved example of rational equations

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

Inverting the equation

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

Apply fraction cross-multiplication

$3\left(x+1\right)=2\left(x-1\right)$

4

Solve the product $3\left(x+1\right)$

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

Solve the product $2\left(x-1\right)$

$3x+3=2x-2$
6

Group the terms of the equation by moving the terms that have the variable $x$ to the left side, and those that do not have it to the right side

$3x-2x=-2-3$
