Question

ax+by+c=0 where a b c are real numbers is called a linear equation in two variables x and y if

Answer 1

Answer:

ax+by+c=0, where;

a,b, and, c are real numbers is called a liner equation in two variables 'x' and 'y'...

Only if

a≠0

Explanation :

If, a=0

Then, (0)x+by+c=0

by+c=0

Then, the linear equation no more sustains as that in two variables, rather in just one variable.

Answer 2

Given : ax+by+c=0 where a b c are real numbers is called a linear equation in two variables x and y

To Find : Condition for a and b

Solution:

ax+by+c=0​

equation which can be put in the form ax + by + c = 0, where a, b and c are real numbers, and a and b are not both zero, is called a linear equation in two variables

ax + by + c = 0  जहाँ a, b और c वास्तविक संख्याएँ हैं, ताकि a# 0 और b # 0 हो, दो चरों.  में एक रैखिक समीकरण

a# 0 और b # 0 ​  is the correct answer
