Question

How the concept of linear equations in two variables developed

Answer 1

Answer:

So, any 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. This means that you can think of many many such equations. ... (ii) The equation x – 4 = 3 y can be written as x – 3 y – 4 = 0.
