(x-4)/6 = (x+5)/5

\(\frac{x-4}{6}=\frac{x+5}{5}\)     Multiply crosswise

\(5x-20=6x+30\)  Change of sides with change of sign

\(5x-6x=30+20\)   add

\(-x=50\)   Multiply on both sides -1

\(x=-50\)

\(x = {-b \pm \sqrt{b^2-4ac} \over 2a}\)    

\(\large x = {-1 \pm \sqrt{1+4*0.5*9} \over -1}\)

 \(\large x=\frac{-1\pm\sqrt{19}}{-1}\)

\(x_1=1-\sqrt{19}=-3.3588989\)
