$\bf \cfrac{x^5y^3}{x^2-x-6}\cdot \cfrac{x^2-9}{x^2y^4}\implies \cfrac{x^5y^3}{x^2-x-6}\cdot \cfrac{\stackrel{\textit{difference of squares}}{x^2-3^2}}{x^2y^4} \\\\\\ \cfrac{x^5y^3}{~~\begin{matrix} (x-3) \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~(x+2)}\cdot \cfrac{~~\begin{matrix} (x-3) \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~(x+3)}{x^2y^4}\implies \cfrac{x^5y^3}{x+2}\cdot \cfrac{x+3}{x^2y^4}$

$\bf \cfrac{x^5y^3}{x^2y^4}\implies \cfrac{x^5x^{-2}}{y^4y^{-3}}\cdot \cfrac{x+3}{x+2}\implies \cfrac{x^{5-2}}{y^{4-3}}\cdot \cfrac{x+3}{x+2}\implies \cfrac{x^3(x+3)}{y(x+2)}\implies \cfrac{x^4+3x^3}{yx+2y}$

Solve for w. 5w + 9z = 2z + 3w w = z w = z w = –2z w = –7z

In-s [12.5K]

We have been given an equation and we are asked to find value of w from our given equation.

$5w+9z=2z+3w$

First of all we will subtract 3w from both sides of our equation.

$5w-3w+9z=2z+3w-3w$

$5w-3w+9z=2z$

Now let us subtract 9z from both sides of our equation.

$5w-3w+9z-9z=2z-9z$

$5w-3w=2z-9z$

$(5-3)w=(2-9)z$

$2w=-7z$

Now let us divide both sides of our equation by 2.

$\frac{2w}{2}= \frac{-7z}{2}$

Upon cancelling 2 from left side of our equation we will get,

$w=\frac{-7}{2} z$

Therefore, we can see that $w=\frac{-7z}{2}$ .
