Question: Check whether 0,2 is a solution of the equation x-2y=4?
: Given, x-2y=4
To find 0,2 is a solution of the equation or not, x=0 and y=2.
Substituting the values of x and y in the LHS of the equation, we get,
x-2y=0-2×2 =-4 ≠RHS
LHS≠RHS
Hence, 0,2 is not a solution of the equation x-2y=4.

Question: Check whether 2,0 is a solution of the equation x-2y=4?
: Given, x-2y=4
2,0 is a solution of the equation.
So, x=2 and y=0. Substituting the values of x and y in the LHS of the equation, we get, x-2y =2-2×0 =2-0
=2≠RHS
Therefore, LHS≠RHS
Hence, 2,0 is not a solution of the equation x-2y=4.

### NCERT Solutions Class 9 Maths Chapter 4: Description

Linear Equation in Two Variables is also known as an equation that has two unknown variable quantity and its degree is two. The degree one means that equation like an equation x + y = 3 or x + 2y – z =7. Note that these equations has got only two variables. If it has three variables like x + 2y – z = 7 then it is a linear equation with three variables. In this chapter, you will deal with these kinds of equations.
