 Difficult Problems

Solved example of rational equations

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

Inverting the equation

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

Apply fraction cross-multiplication

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

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

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

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

$3x+3=2x-2$

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

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

Subtract the values $-2$ and $-3$

$3x-2x=-5$

Combining like terms $3x$ and $-2x$

$x=-5$
