Question

Check wheather the equation $\frac{x}{7y}+3=1$ is linear or not. If yes find the value of $y$ when $x=2$.

• A. Yes, $y=\frac{-1}{7}$
• B. No, it is not a linear equation
• C. Yes, $y=\frac{1}{7}$

Answer 1

The correct option is A Yes, $y=\frac{-1}{7}$

Yes the given equation is linear equation.
On simplifying we get,
$\frac{x}{7y}=-2$
$\Rightarrow x=-14y$
Putting $x=2$
$\Rightarrow 2=-14y$
$\Rightarrow \frac{-1}{7}=y$
