Question

The value of a when y= 3 is expressed in the form of ax + by+c = 0 is​

Answer 1

$Given \: Linear \: equation \: in \:two \\ variables \: is : \pink {ax + by + c = 0}$

$To \: find \: value \: a \: when \: y = 3 ,\\we \: have \: substitute \: y = 3 \: in \:the \: Equation$

$ax + b \times 3 + c = 0$

$\implies ax + 3b + c = 0$

$\implies ax = - (3b+c)$

$\implies a = \frac{- (3b+c)}{x}$

Therefore.,

$\red { Value \:of \: a \:when \:y = 3 } \green { \:is\: \frac{-(3b+c)}{x}}$
