Question

Express the following linear equations in the form $ax+by+c=0$ and indicate the values of a, b and c in each case:

(i) $3x=-7y$ (ii) $y-5=0$

(iii) $4=3x$

Answer 1

(i) $3x=-7y$

$\Rightarrow 3x+7y+0=0\text{Here}a=3,b=7,c=0$
$\text{Here}a=2,b=0,c=3$

(ii) $y-5=0$

$\Rightarrow 0x+y-5=0\text{Here}a=0,b=1,c=-5$

(iii) $4=3x$

$\Rightarrow 3x-4=0\Rightarrow 3x+0y-4=0\text{Here}a=3,b=0,c=-4$
