i am solving a set of simlutaneous equations. they are as follows:
[SIZE=14] x[SIZE=1] 2[SIZE=14] +4y[SIZE=1] 2[SIZE=14] =16
[SIZE=14] xy=4
the small numbers indicate exponents. i have two of these for my math hw, but for now, if anyone knows how to solve this one, pleasse help, fast
edit- this isnt coming out right, so in words-
x squared + 4y squared= 16
xy=4
help please
