in this chapter u told us that a linear equation has infinetely many solutions , if a equation does not have infinetely many solutions does it can be called as a linear equation
A linear equation in 2 variables has infinitely many solutions. If for the given equation you are getting only 1 solution, then that equation is a linear one, but it will be an equation in only 1 variable. A linear equation in 1 variable has only 1 solution.
