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?

Question

the equations are

6x + 3y = 14
3x + 2y = 10

Answer 1

Tatum should multiply the second equation by 2 in order to eliminate the variable y when adding the equations.

This gives the following system of equations:

6x + 3y = 14
6x + 4y = 20
