Answer 1

$\red{\large {\underline{ \underline{ \star \: {Given}}}}}$

Find the solution of the Line equation 3x + 4y =12.

$\red{\large {\underline{ \underline{ \star \: {Answer}}}}}$

Taking x = 1.

$3x + 4y = 12. \\ \\ 3(1) + 4y = 12. \\ \\ 3 + 4y = 12. \\ \\ y = \frac{9}{4} .$

Case II

Taking x = 2.

$3(2) + 4y = 12. \\ \\ 6 + 4y = 12. \\ \\ 4y = 6. \\ \\ y = \frac{ \cancel6}{ \cancel4} \\ \\ y = \frac{3}{2.}$
