To eliminate a variable in the system of equations, we can multiply one equation by a constant and then add it to the other equation. Let's multiply the first equation by 5 and the second equation by 2:
Now, we can add the two equations to eliminate the variable x:
Therefore, the equation that could be the result of multiplication and addition to eliminate a variable in the system of equations is
