If you isolated "X" in the second equation, you would take the answer you got (10) and plug it into the first equation to find "Y".

which would give you y=4/15

Solution:
x=10 from second equation
y=4/15 from first equation

i think thats what your looking for, if not im not sure how much help i'll be, sorry ):
