As you see in the X coloum they have already given you the number for x. So what you do is plug in -2 for x. so it would be 6(-2)+3y=18. it will be -12+3y=18. Put like terms on the same side. Meaning you would add 12 to both sides. it will end up being 3y=30. Divide both sides by 3 so the variable can stay alone and that would mean y=10. So when x=-2, y=10. You can always plus it back in the equation to double check if the answer is right. 6(-2)+3(10)=18. Do the same thing for the remaining ones and youre all set!!! Hope th
