Question 1057941

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.
<pre>{{{x^2 + y^2 = 32}}} -------- 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!
