We want to find the solution $x,y$ that solves the two following equations at the same time: $$2x+3y=18,$$ $$2x-1y=2.$$ What are the two equivalent equations we get by multiplying the first equation by 1 and the second equation by 3?

  • $$4x-3y=18,$$ $$6x-3y=6.$$
    $$4x+3y=18,$$ $$6x-3y=6.$$
    $$2x+3y=18,$$ $$6x-3y=6.$$
    $$2x-3y=18,$$ $$6x-3y=6.$$
