Answer 2

$\sf\small\red{Given:-}$

$\sf\rightarrow \: x = 1$

$\sf\rightarrow \: y = 2$

$\sf\small\red{Find:-}$

$\sf\rightarrow Find \: the \: equation \: {a}^{2} x + ay = 3$

$\sf\small\red{Solution:-}$

$\sf\rightarrow \: a²x + ay = 3$

$\sf\rightarrow \: So, x = 1 \: and \: y = 2$

$\sf\rightarrow \: 2a² + a - 3 = 0$

$\sf\rightarrow2a² - 2a + 3a - 3 = 0$

$\sf\rightarrow2a( a - 1) + 3 ( a - 1) = 0$

$\sf\rightarrow( 2a + 3) ( a - 1) = 0$

So, a = 1 and a = -3/2
