You just combine the like terms. Put the x's together and then put the y's together. When you have fractions like the ones in this problem, you have to find a common denominator and then you're done.

2/7x+ 1/3x
=(2/7x)3+(1/3x)7
=6/21x+7/21x
=13/21x
1/2y+3/4y
=(1/2y)2+3/4y
=2/4y+3/4y
=5/4y
13/21x+5/4y
