x = y - a

x = a - y

x = y + a

x = ay

x = y - a

$x\ =\ \frac{y}{a}$

x = y + a

x = ay

x = y - a

$x\ =\ \frac{y}{a}$

$x\ =\ \frac{a}{y}$

x = ay

x = y - a

$x\ =\ \frac{y}{a}$

$x\ =\ \frac{a}{y}$

x = ay

$x\ =\ \frac{y}{a}-3$

$x\ =\ \frac{y-3}{a}$

$x\ =\ \frac{a-3}{y}$

$x\ =\ \frac{y}{a}-3$

$x\ =\ \frac{y}{3}+a$

$x\ =\ \frac{y+a}{3}$

$x\ =\ \frac{y-3}{a}$

$x\ =\ \frac{y}{a}-3$

$x\ =\ \sqrt{y-a}$

$x\ =\ \sqrt{y}-a$

$x\ =\ \sqrt{y+a}$

$x\ =\ \sqrt{y}+a$

$x\ =\ \sqrt{y-a}$

$x\ =\ \sqrt{y}-a$

$x\ =\ \sqrt{y+a}$

$x\ =\ \sqrt{y}+a$

$x\ =\ \sqrt{y}$

$x\ =\ y^2$

$x\ =\ \sqrt{y}-a$

$x\ =\ y^2-a$

$x\ =\ \left(y-a\right)^2$

$x\ =\ \sqrt{y-a}$
