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

Answer 1

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 \( n = 2 \).
