Explanation Subtracting equations, x − 2x = 2 − − 1 −x = 3 x = − 3 y = 2 −x = 2 − −3 = 5 Check −3 5 = 2 √Step1 The first step is to multiply or divide both the linear equations with a nonzero number to get a common coefficient of any one of the variables in both equations Step2 Add or subtract both the equations such that the same terms will get eliminated

Therefore, x = 1 and y = 2 is the solution of the set of equations 2x y = 4 and 5x – 3y = 1 Elimination Method Examples Take a look at the elimination method questions Example 1 Solve the following equations using the addition method 2x y = 9 3x – y = 16 Solution If you add down, the y variables will cancel out 2x y = 9 3x – y = 16 _____ 5x = 25Solution x – y = 5 (1) 3x 2y = 25 (2) The coefficient of y in the first equation is 1, the coefficient of y in the second equation is 2 So, we have to multiply the first equation by 2 2x 2y = 10 3x 2y = 25Solve (1) and (2) using elimination method x y = 548 (1) 2x y = 750 (2) In the above two equations, y is having the same coefficient, that is 1 Multiply the first equation by 1 to get the coefficient of 1 And keep the second equation as it is Then, we have x y = 548 2x y = 750 We can add the above two equations and eliminate y Then, we have x = 2 Step 4 Substitute

Now we can divide both sides by negative 2 And we are left with y is equal to positive 2x, right, that's positive 2x, minus 25 So let's graph that The yintercept is negative 25 So negative 25 right there, and then it has a slope of 2 So if we move up 1, if we move up in the xdirection, if we move to the right 1 in the positive xSolution Look at the x coefficients Multiply the first equation by 4, to set up the xcoefficients to cancel Now we can find Take the value for y and substitute it back into either one of the original equations The solution is Example 3 Solve the system using elimination method
