Answer:

x=11

Step-by-step explanation:

You do 38/3x+3 and 19/x+7 and then cross mulitply and get 57x+57=38x+266. Then yoy subtract 57 from 266 and get 57x=38x+209. Now you have to subtract 38 from 57 and then answer will be 19. So now you have 19x=209. Finally you divide 209 by 19 and get x=11. Good luck!

Find what n equals 8(2n-2) = 4 - 4n (explanation please)

slavikrds [6]

Answer:

$\huge\boxed{n=1}$

Step-by-step explanation:

In order to find the value of n that satisfies this equation, we can perform a series of algebraic steps on it to solve for n.

$8(2n-2) = 4- 4n$
<em>Distribute in the 8 on the left side:</em>
<em /> $16n-16=4-4n$ <em> </em>
<em>Add 4n to both sides</em>
$20n-16=4$
<em>Add 16 to both sides</em>
$20n = 20$
<em>Divide both sides by 20</em>
$n=1$

Therefore, n=1 is the value of n that satisfies this equation.

Hope this helped!
