Is r = 12 a solution to this equation?

12 +
r
= 24
Yes or no

1 answer

To determine if \( r = 12 \) is a solution to the equation \( 12 + r = 24 \), we can substitute \( r \) with 12.

So, we have:

\[ 12 + 12 = 24 \]

Calculating the left side:

\[ 24 = 24 \]

Since both sides of the equation are equal, the answer is yes, \( r = 12 \) is a solution to the equation.
