Question #5eee2
1 Answer
I will assume that you are treating
We will solve the first equation for
#x = yab#
Now, substitution into the second equation gives:
#a^2 by + by = a^2 + b^2#
Factor out
#y(a^2 b + b) = a^2 + b^2#
And lastly, divide:
#y = (a^2 + b^2)/(a^2 b + b)#
So there's
#y = x/(ab)#
Substitute into the second equation:
#ax + x/a = a^2 + b^2#
Factor
#x(a + 1/a) = a^2 + b^2#
And lastly, divide to isolate
#x = (a^2 + b^2)/(a + 1/a)#
If we would like, we can rewrite
#x = (a^2 + b^2)/((a^2 + 1)/a)#
And then simplify a bit, just to make the equation a little prettier:
#x = (a^3 + b^2 a)/(a^2 + 1)#
