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 – ...
This chapter discusses linear equation in two variables. Elementary algebra deals with equations such as 3 x = 5, x 2 y = 8, and x + 3 y 2 z = 14. These are classed as first-degree equations, also called linear equations, because their unknown quantities appear no more than once in...
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 ...
Solve 3x - 2y = 4 and 4x - y = 7 and verify it using linear equations in two variables calculator. Solution: 3x - 2y = 4 ---> (1) 4x - y = 7 ---> (2) From (2), y = 4x - 7 ---> (3) Substitute (3) in (1), 3x - 2(4x -...

Inconsistent System:Unlike independent systems, the inconsistent system has no solution. Consider two parallel lines in a graph that will never intersect; hence, it is an inconsistent system of linear equations in two variables. Dependent System:On the other hand, a dependent system has infinite so...
