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?
6x+3y=14
3x+2y=10
1. −2
2. 2
3. 6
4. -1/2
To eliminate a variable when adding the equations, Tatum should multiply the second equation by 2.
So the answer is 2.
