Ifound:
#x=3#
#y=0#

Explanation:

You can solve the System formed by the two equations trying to find values of #x# and #y# that simultaneously satisfy the two equations.
Isolate #x# from the first equation:
#x=3+y# substitute for #x# into the second equation:
#(3+y)-2y=3#
#3+y-2y=3#
So: #y=0#
Substitute back into the first equation:
#x=3+0=3#
