Let's use elimination by addition/subtraction:

Mult. the 2nd eqn by 2, obtaining x/2 + 4y/3 = 10.  Now subtract the first eqn from this result:

  x/2 + 4y/3 = 10
-(X/2+   y/3 =   4
----------------------
           3y/3 = 6, or   y = 2.  

Now subst. 2 for y in either of the original equations and solve the result for x:

x/4 + 2(2)/3 = 5         Mult all 3 terms by 12 to eliminate the fractions:

3x + 16 = 60  =>  3x = 44, and so x = 44/3.

The solution is (44/3, 2).
