Question

defination of linear equation in two variable

Answer 1

Hey mate here is your answer

Each linear equation in two variables defined a straight line. To solve a system of two linear equations in two variables, we graph both equations in the same coordinate system. The coordinates of any points that graphs have in common are solutions to the system, since they satisfy both equations.

Hope this answer will help you!!

Answer 2

when you solve 2 equations simultaneously,the eqns are linear eqn in 2 variables.

It involves 2 eqns and 2 variables.

For example:
x+y=23
2x-y=4
