5+n+10=205+n+10=20
n = 5
5 plus n plus 10 is equal to 20 n = 5
5(n+10)=205(n+10)=20
n = -6
5 times open paren n plus 10 close paren is equal to 20 n = -6
5+10n=205+10n=20
n = 1.5
5 plus 10 n is equal to 20 n = 1.5
5n+10=205n+10=20
n = 2
5 n plus 10 is equal to 20 n = 2

To solve the problem, let’s first break down the statement: "five times a number added to 10 is 20."
This can be written mathematically as:
\[ 5n + 10 = 20 \]
where \( n \) is the unknown number.
Now, we can solve for \( n \):
1. Subtract 10 from both sides:
\[ 5n + 10 - 10 = 20 - 10 \]
\[ 5n = 10 \]
2. Divide both sides by 5:
\[ n = \frac{10}{5} \]
\[ n = 2 \]
So the correct equation is \( 5n + 10 = 20 \) and the unknown number is \( n = 2 \).
This can be written mathematically as:
\[ 5n + 10 = 20 \]
where \( n \) is the unknown number.
Now, we can solve for \( n \):
1. Subtract 10 from both sides:
\[ 5n + 10 - 10 = 20 - 10 \]
\[ 5n = 10 \]
2. Divide both sides by 5:
\[ n = \frac{10}{5} \]
\[ n = 2 \]
So the correct equation is \( 5n + 10 = 20 \) and the unknown number is \( n = 2 \).
