PT <=>$(\sqrt{8x+1}-5)+(\sqrt{3x-5}-2)=(\sqrt{7x+4}-5)+(\sqrt{2x-2}-2)$
<=>$\frac{8x-24}{\sqrt{8x-1}+5}+\frac{3x-9}{\sqrt{3x-5}+2}=\frac{7x-21}{\sqrt{7x+4}+5}+\frac{2x-6}{\sqrt{2x-2}+2}$
<=>$\frac{8(x-3)}{\sqrt{8x+1}+5}+\frac{3(x-3)}{\sqrt{3x-5}+2}=\frac{7(x-3)}{\sqrt{7x+4}+5}+\frac{x(x-3)}{\sqrt{2x-2}+2}$
