Tatum wants to solve the following system of equations by using the elimination method. What integer should she multiply the second equation by to eliminate a variable when you add the equations?

To eliminate variable x when adding the equations, Tatum should multiply the second equation by -2. This will make the coefficients of x in both equations equal and they will cancel out when added together.
