Apply the formula: $\frac{a}{x}=\frac{b}{y}$$\to \frac{x}{a}=\frac{y}{b}$, where $a=2$, $b=3$, $x=x+1$ and $y=x-1$
$\frac{x+1}{2}=\frac{x-1}{3}$

$\frac{x+1}{2}=\frac{x-1}{3}$
Learn how to solve equations rationnelles problems step by step online. 2/(x+1)=3/(x-1). Apply the formula: \frac{a}{x}=\frac{b}{y}\to \frac{x}{a}=\frac{y}{b}, where a=2, b=3, x=x+1 and y=x-1. Apply the formula: \frac{a}{b}=\frac{c}{f}\to af=bc, where a=x+1, b=2, c=x-1 and f=3. Apply the formula: x\left(a+b\right)=xa+xb, where a=x, b=1, x=3 and a+b=x+1. Apply the formula: x\left(a+b\right)=xa+xb, where a=x, b=-1, x=2 and a+b=x-1.
