Question

On expressing the equation $5x+2y=28$ in the general form of a linear equation in two variables $ax+by+c=0,$ the value of $c$ equals .

Answer 1

Consider the equation $5x+2y=28.$
$\Rightarrow 5x+2y-28=0$
Comparing this equation with the general form of linear equation in two variables $ax+by+c=0,$ we get
$a=5,b=2$ and $c=-28.$
Thus, the value of $c$ equals $-28.$
