Question

Which of the following are linear equations in two variables X+Y=2

Answer 1

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.

Since The coefficient of X and Y is 1

Hence X+Y = 2 are not linear equations in two variables

Hope it helps you :)
