3x+y=10 x-y=2 elimination method
3x+y=10 x-y=2 elimination method-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 method9/3/16 If the linear equation in two variables 2x –y = 2, 3y –4x = 2and px–3y = 2are concurrent, then find the value of p If ܽa b = 35 and a − b = 13, where a > b, then find the value of a and ܾb

2/5/19 3x 7y 10 = 0 can be written as 3x 7y = 10 (1) y 2x 3 = 0 can be written as y 2x = 3 (2) Multiplying (1) by 2 and (2) by 3 we get, 6x 14y = (3) 3y 6x = 9 (4) Adding eq (3) and eq (4), 11y = 11 Hence, y = 1 Using y's value in (4) 3 (1) 6x = 9 3 6x = 9 6x = 6 Hence, x = 112/3/18 2x y = 5 3x y = 10 By solving this equation by eliminating method y and y would get canceled, leaving 2x 3x = 5 10 5x = 15 x = 3 By putting value of x in equation 1,Xy=14 3xy=10 Answered by a verified Math Tutor or Teacher We use cookies to give you the best possible experience on our website By continuing to use this site you consent to the use of cookies on your device as described in our cookie policy unless you have disabled them
By adding the two equations together you eliminate the y variable which allows you to solve x = 6 Alternately, subtract one equation form the other eliminating the x and allowing y = 4 Explanation Given 1 XXXx y = 10 2 XXXx −y = 2 Add 1 and 2 3 XXX2x = 12 → 4 XXXx = 6 Subtract 2 from 1 5 XXX2y = 8 → XXXy = 4We can multiply the first equation by to get an equivalent equation that has a term Our new (but equivalent!) system of equations looks like this Adding the equations to eliminate the terms, we get Solving for , we get Plugging this value back into our first equation, we solve for the other variable The solution to the system is ,27/7/18 Solving 3x 4y =10 and 2x 2y =2 by elimination method Let 3x 4y =10 (1) and 2x 2y =2 (2) Multiply Equation (2) by 2 to make the coefficients of y equal Then we get the equation 4x – 4y = 4 (3) Add Equation (1) and (2) to eliminate y, because the coefficients of y are the same So, we get
