Question

I don't understand if this equation is a linear equation or not. Can you please help me?

Answer 1

we have the equation

$\frac{x}{4}-\frac{y}{3}=1$

To remove the fractions, multiply both sides by (4*3=12)

$\begin{gathered} \frac{12x}{4}-\frac{12y}{3}=12 \\ 3x-4y=12 \\ 4y=3x-12 \\ y=\frac{3}{4}x-3 \end{gathered}$

this is the equation of a line

that means

is a linear equation
