Question

There is only one variable in equation 3x = 0 hence it can' t be called equation in two variables true or false?​

Answer 1

Answer:

Step-by-step explanation:

False

Answer 2

Answer:

True .

Step-by-step explanation:

Given :- $3x = 0$

To find :- reason of equation ( above mentioned ) cannot be termed as equation in two variables .

Solution :-

Given equation is $3x = 0$

• We know ,

general form of equation for 2 variables , $ax + by + c = 0$

where , x and y are two variables

hence equation can be called as equation with two variables .

• The above given eqn. $3x = 0$  , does not have second variable ' y ' .
• The equation has only one solution for x , i.e. x = 0 ( as far as this problem is concerned )
• Hence $3x = 0$  is not equation in 2 variables .

answer is True .
