To determine The solution of linear equations 2 x − 1 3 + y + 2 4 = 4 and x + 3 2 − x − y 3 = 3 using elimination method. Explanation Given: The provided system of linear equations is { 2 x − 1 3 + y + 2 4 = 4 x + 3 2 − x − y 3 = 3 . Procedure used: “Solving system of linear equations by elimination: (1) If the equations are not in the standard form, then they are converted accordingly into a standard form. (2) The variable to be eliminated is recognized from the given equations in the system. (3) After obtaining the LCM (lowest common multiple) of coefficients of the variable to be eliminated, the equations are multiplied with appropriate multipliers so that the coefficients in each equation become additive inverses and adding the new equations will result in a fresh equation with the decided variable to been eliminated. (4) The equation in step (3) is solved obtaining value of remaining variable. (5) The value of variable in step (4) is substituted to the equation in any of the given system equations. (6) Solving the equation obtained in step (5) gives the value of variable eliminated in step (3). (7) The correctness of solution is asserted by substituting back the values in given equations of the system.” Calculation: The given system of the linear equation is as follows: 2 x − 1 3 + y + 2 4 = 4 ...... ( 1 ) x + 3 2 − x − y 3 = 3 ...... ( 2 ) Step 1: Since the given equations are not in standard form, multiply equation (1) by 12 . 12 ( 2 x − 1 3 + y + 2 4 = 4 ) 8 x − 4 + 3 y + 6 = 48 8 x + 3 y = 48 − 2 8 x + 3 y = 46 ...... ( 3 ) Multiply with 6 on both sides of equation (2)
