Is \( r=-6 \) a solution to this equation? \( -242=10 r \)

To check if \( r = -6 \) is a solution to the equation \( -242 = 10r \), we can substitute \( r \) with \( -6 \): \[ 10(-6) = -60 \] Now, comparing the two sides of the equation: \[ -242 \neq -60 \] Thus, \( r = -6 \) is not a solution to the equation. Now, let's double-check by solving for \( r \): \[ -242 = 10r \implies r = \frac{-242}{10} = -24.2 \] See? The solution is \( -24.2 \), making it clear that \( r = -6 \) does not fit the bill.
