The simplified form of the provided equation is $8x+34y$.
Consider the provided equation $4\left( 5x+4y \right)-2\left( 6x-9y \right)$ Simplify this equation as follows: \begin{align} & \left( 20x+16y \right)-\left( 12x-18y \right) \\ & \left( 20x-12x \right)+\left( 16y+18y \right) \\ & 8x+34y \\ \end{align} The simplified equation is $8x+34y$.
