What will we be multiplying by to solve for x?

 $\frac{x+1}{3\left(x-2\right)}=\frac{5x}{6}+\frac{1}{x-2}$  

• x+1

• 5x

• 6

• 3

• x-2

 $\frac{x+1}{3\left(x-2\right)}=\frac{5x}{6}+\frac{1}{x-2}$  

 $0=5x^2-12x+4$  

 $\frac{x+1}{3\left(x-2\right)}=\frac{5x}{6}+\frac{1}{x-2}$

What does this mean for our solutions we found?

 $x=2\ and\ x=\frac{2}{5}$  

 $x=\frac{2}{5}$  

 $-\frac{2}{x+3}+\frac{4}{x-2}=\frac{1}{x-2}$  

 $-\frac{2}{x+3}+\frac{4}{x-2}=\frac{1}{x-2}$  

 $x^2-5x+6$  

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

Multiply by (x-2)(x-3)!

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

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