4. Linear Equations in Two Variables

easy

Express the following linear equations in the form $ax + by + c = 0$ and indicate the values of $a$, $b$ and $c$ in each case : $x=3 y$

Option A

Option B

Option C

Option D

Solution

We have $x=3 y$ $ \Rightarrow x-3 y=0$

$ \Rightarrow (1) x+(-3) y+0=0$

Comparing with $a x+b x+c=0,$ we get $a=1, b=-3$ and $c=0$
