Let's go:

$\frac{32}{6x + 6} = \frac{24}{9x - 9} \\\\ 32.(9x - 9) = 24.(6x + 6) \\\ 288x - 288 = 144x + 144 \\\ 288x - 144x = 144 + 288 \\\ 144x = 432 \\\ x = 3$

I hope I helped you.

Step-by-step explanation:

$\frac{5}{4t}-\frac{t+4}{10t^2}=\frac{5\left(10t^2\right)-4t\left(t+4\right)}{40t^3}=\frac{2t\left(25t-2\left(t+4\right)\right)}{40t^3}=\frac{\left(25t-2t-8\right)}{20t^2}=\frac{23t-8}{20t^2}$

How to simplify this expression ?

Musya8 [376]

Answer:

$\large \boxed{\sf \ \ \dfrac{1}{x^2}+\dfrac{1}{x^2+x}=\dfrac{2x+1}{x^2(x+1)} \ \ }$

Step-by-step explanation:

Hello,

This is the same method as computing for instance:

$\dfrac{1}{2}+\dfrac{1}{3}=\dfrac{3+2}{2*3}=\dfrac{5}{6}$

We need to find the same denominator.

Let's do it !

For any x real different from 0, we can write:

$\dfrac{1}{x^2}+\dfrac{1}{x^2+x}=\dfrac{1}{x^2}+\dfrac{1}{x(x+1)}\\\\=\dfrac{x+1+x}{x^2(x+1)}=\dfrac{2x+1}{x^2(x+1)}$

Hope this helps.

Do not hesitate if you need further explanation.

Thank you
