Explanation Procedure used: Elimination Method: Step 1: Select two of the equations and eliminate one of the variables from one of the equations. Select any two other equations and eliminate the same variable from one of the equations. Step 2: Step 1 will leave two equations with two unknowns. Solve this system by eliminating one of the variable. Step 3: Use the two known values of the variables found in Step 2 to find the value of the third variable. Step 4: Check the answer. Calculation: The given system is, { 2 x − y = 2 − x + 5 z = 3 − y + 10 z = 8 . The equations are: 2 x − y = 2 (1) − x + 5 z = 3 (2) − y + 10 z = 8 (3) Multiply the equation (2) by 2 and add with equation (1) 2 x − y = 2 − 2 x + 10 z = 6 _ − y + 10 z = 8 That is, − y + 10 z = 8 . (4) Subtract equation (4) from equation (3). − y + 10 z = 8 − − y + 10 z = 8 _ 0 = 0 From the above, it can be observed that the system of equation is dependent and has infinitely many solutions. Since the equation (4) and (5) are same, equation (4) is enough for further calculations. Now, solve the equation (4) for y in terms of z . − y + 10 z = 8 − y = 8 − 10 z y = 10 z − 8 Substitute y = 10 z − 8 in the equation (1)
