first, get rid of those pesky fractions and you have
x+3y = 2
2x+3y = 6
now subtract the 1st from the 2nd and you have
x = 4
Then plug that into either equation to find y:
4+3y = 2
y = -2/3
final step: check those values in each of the original equations to make sure you have not made a mistake somewhere.
