40 LINEAR EQUATIONS IN TWO VARIABLES MATHEMATICS–IX Example 6. Find a if x = 3, y = 1 is a solution of the equation 3x – y = a. Solution. Given 3x – y = a As x = 3, y = 1 is a solution of this given equation, it must satisfy it. 3 (3) –1 = a a = 9 – ...
In order for a linear system to have a single, unique solution, there must be at least as many equations as there are variables. Even so, this does not guarantee a single, unique solution.In this section, we will look at systems of linear equations in two variables, which consist of ...
