4. Linear Equations in Two Variables
easy

नीचे दिए गए समीकरणों को $a x+b y+c=0$ के रूप में लिखिए और प्रत्येक स्थिति में $a, b$ और $c$ के मान बताइए

$(i)$ $2 x+3 y=4.37$

$(ii)$ $x-4=\sqrt{3} y$

$(iii)$ $4=5 x-3 y$

$(iv)$ $2 x=y$

Option A
Option B
Option C
Option D

Solution

$(i)$ $2x + 3y = 4.37$ can be written as $2x + 3y -4.37 = 0$.

Here $a = 2$, $b = 3$ and $c = -\, 4.37$.

$(ii)$ The equation $x-4=\sqrt{3} y$ can be written as $x-\sqrt{3} y-4=0 .$

Here $a=1$, $b=-\,\sqrt{3}$ and $c=-\,4$

$(iii)$ The equation $4=5 x-3 y$ can be written as $5 x-3 y-4=0 .$

Here $a=5, b=-3$ and $c=-\,4 .$

$(iv)$ The equation $2x = y$ can be written as $2x -y + 0 = 0$.

Here $a = 2, \,b = -\,1$ and $c = 0.$
