We can write the statement "Y is proportional to the value of X ", which means that if X is double, Y is also doubled etc, as follows:
$Y \propto X$
Y is proportional to X

#### Explanation:
${x}^{2} = 8 x$
Add $8 x$ to both sides:
$\implies {x}^{2} - 8 x = 8 x - 8 x$
$\implies x \left(x - 8\right) = 0$ (factrorization)
$\implies {x}_{1} = 0 \mathmr{and} {x}_{2} = 8$
