What is two more than 4 times a number is -18 translated and solved

Brrunno [24]

Answer:

n=-5

Step-by-step explanation:

Let "n" represent the unknown number.

So, the equation asks for 4n and two more, or +2, that is all equal to -18.

So, your equation will be:

$4n+2=-18$

First, subtract 2 from both sides:

$4n+2-2=-18-2\\4n=-20$

Then, divide both sides by 4:

$\frac{4n}{4}=\frac{-20}{4}\\n=-5$

Therefore, n=-5.

Answer:

Hey there!

$\frac{3+2-4^2(7)-5+2}{16-6(6)^2}$

$\frac{3+2-16(7)-5+2}{16-6(36)}$

$\frac{3+2-112-5+2}{16-216}$

$\frac{-110}{-200}$

$\frac{11}{20}$

Let me know if this helps :)
