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:
[tex]4n+2=-18[/tex]
First, subtract 2 from both sides:
[tex]4n+2-2=-18-2\\4n=-20[/tex]
Then, divide both sides by 4:
[tex]\frac{4n}{4}=\frac{-20}{4}\\n=-5[/tex]
Therefore, n=-5.
