Answer:

  3

Step-by-step explanation:

Assuming your two equations are ...

  • 6x -3y = 3
  • -2x +y = 14

You want to find the multiplier k such that ...

  6 + (-2)k = 0 . . . . total x-coefficient after the equations are combined

Dividing by 2 gives ...

  3 - k = 0

  3 = k . . . . . . add k

The multiplier needed is 3.
