An equations of the form Ax + By + C = 0 is called a linear equation in two variables x and y where A, B, C are real numbers. Two linear equations in the same two variables are called a pair of linear equations in two variables. Standard form of linear equations in two variables. a1x + b1y + c1 = 0, a2x + b2y + c1 = 0 where a1, a2, b1, b2, c1, c2ar...
Every linear equation in two variables graphically represents a line and each solution (x, y) of a linear equation in two variables, ax + by + c = 0, corresponds to a point on the line representing the equation, and vice versa.
There are infinitely many solutions of each linear equation. So, we choose at least any two values of one variable & get the value of other variable by substitution, i.e; Consider; Ax + By + C = 0 We can write the above linear equation as: Here, we can choose any values of x & can find corresponding values of y. After getting the values of (x, y) w...
Coordinate of the point (x, y) which satisfy the system of pair of linear equations in two variables is the required solution. This is the point where the two lines representing the two equations intersect each other. There are two methods of finding solution of a pair of Linear equations in two variables. (1) Graphical Method : This method is less...
Consider the standard form of linear equations in two variables. a1x + b1y + C1 = 0; a2x + b2y + c2 = 0 While solving the above system of equation following three cases arise. (i) If ; system is called consistent, having unique solution and pair of straight lines representing the above equations intersect at one point only (ii) If ; system is calle...
Consider the following system of equation a1x + b1y + c1 =0; a2x + b2y + c1 =0 There are following three methods under Algebraic method to solve the above system. (a) Find the value of one variable, say y in terms of x or x in terms of y from one equation. (b) Substitute this value in second equation to get equation in one variable and find solutio...
For the pair of Linear equations intwo variables: a1x + b1y + C1 = 0 a2x + b2y + c2 = 0 Consider the following diagram. Solve it to get the solution, provided a1b2 – a2b1≠ 0
Sometimes pair of equations are not linear (or not in standard form), then they are altered so that they reduce to a pair of linear equations in standard form. For example; Here we substitute = p & \frac{1}{y} = q, the above equations reduces to: a1p + b1q = c1 ; a2p – b2q = c2 Now we can use any method to solve them.
