I. $3{x^2} - 7x + 4 = 0$II.$2{y^2} - 9y + 10 = 0$

I. $3{x^2} - 7x + 4 = 0$

$Rightarrow 3{x^2} - 4x - 3x + 4 = 0$

$Rightarrow left( {3x - 4} ight)left( {x - 1} ight) = 0$

$x = frac{4}{3}{ m{or}}1$II. $2{y^2} - 9y + 10 = 0$

$Rightarrow 2{y^2} - 4y - 5y + 10 = 0$

$Rightarrow left( {2y - 5} ight)left( {y - 2} ight) = 0$

$Rightarrow y = frac{5}{2}{ m{or}}2$

$y > x$
