Variable $x$ cannot be equal to $-\frac{11}{3}$ since division by zero is not defined. Multiply both sides of the equation by $20\left(3x+11\right)$, the least common multiple of $3x+11,20$.
$$20\left(2x+5\right)=11\left(3x+11\right)$$
Use the distributive property to multiply $20$ by $2x+5$.
$$40x+100=11\left(3x+11\right)$$
Use the distributive property to multiply $11$ by $3x+11$.
