If either of the coefficients for a variable do not match then multiplication will be needed.

MULTIPLY both members of the second equation by .

You can eliminate the y in THAT system WITHOUT using MULTIPLICATION, simply because the coefficients' absolute values are 1. Just sum the left members and sum the right members, and solve for x.

To solve for y using elimination will be different: MULTIPLY the second equation by 5, and subtract one equation from the other, and then find y. You do it!
