If x2 + y2 = 32 and 2x - 2y = 6, then what is x? If there are two possible answers, then enter the larger of the two.
 -------- eq (i)

Reduce 2x - 2y = 6 by dividing by GCF, 2 to get: x - y = 3___x = 3 + y ---- (ii)

Substitute 3 + y for x in eq (i) to get value(s) for y

Substitute value(s) for y into any of the 2 original equations (equation ii is EASIER) to get value(s) for x

That's it....nothing COMPLEX!
