An equation is said to be linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e a and b respectively, are not equal to zero.
For example, 10x+4y = 3 and -x+5y = 2 are linear equations in two variables.
The solution for such an equation is a pair of values, one for x and one for y which further makes the two sides of an equation equal.
The solution of linear equations in two variables, ax+by = c, is a particular point in the graph, such that when x-coordinate is multiplied by a and y-coordinate is multiplied by b, then the sum of these two values will be equal to c.
Basically, for linear equation in two variables, there are infinitely many solutions.
Example
In order to find the solution of Linear equation in 2 variables, two equations should be known to us.
Consider for Example:
5x + 3y = 30
The above equation has two variables namely x and y.
Graphically this equation can be represented by substituting the variables to zero.

Thank sir aapke jaisa koi school me nahi padhata

[aquaeditz]

Sir 43 me elimination se karenge to x = 1 ayega aur y = b/a is this also correct please share 🙏🏻

[sunnykumar]

Thankyou sir sachi mai aap jaisa hamare school mai koi nhi padhate

[madyash]

Plz start ur video with old intro 😅 request from heart

[slimeworld]

at 25:51 sir there was a sign of (-)in equation 1 and sir at equation 3 u have'nt given the sign of (-) sir plz explain it

[heee-jq]

Sir vo leaved questions doosre method se bhi ho skta h agar aap pin krenge to short me bta dunga ❤❤
