Yes, you just times one of the equations by a numberr to make it cancel out with the other. For instance:

2x + 6 y = 10

4x + 2y = 16

If we multiply the equation 2x + 6 y = 10 by 2 we get the following

2x + 6 y = 10

-2 (2x + 6 y) = - 2 (10)

-4x - 12y = - 20

Now we use this new equation.

-4x - 12y = - 20

4x + 2y = 16

As you can see, you can cancel out the x and solve for y now.
