Express the linear equation $7=3x$ in the form $ax+by+c=0$.
 

 If an equation is written in the form $ax+by+c=0$, it is said to be a linear equation in two variables, where a, b and c are real integers and the coefficients of x and y, i.e. a and b are not equal to zero.

It is given that the linear equation is $7=3x$.

It can be written as,

$\Rightarrow 3x+0.y-7=0$

which is in the form $ax+by+c=0$.

Thus, the linear equation can be expressed in the form $ax+by+c=0$ as $7=3x$.
