Solve this by the elimination method Solution In the elimination method, we just eliminate one variable to find the value of other 3x4y=10 (I) xy=1 (II) (I) 4(II) 3x4y=10 4x4y=4 7x0y = 14 7x = 14; Solve the following systems of linear equations by Gaussian elimination method (i) 2x – 2y 3z = 2, x 2y – z = 3, 3x – y 2z = 1 ← Prev Question Next Question → 0 votes
3x+y=10 x-y=2 elimination method
3x+y=10 x-y=2 elimination method-Y=x^22x2 yx=3 In order to graph y=x^22x2 we complete the square and write it as y1=(x1)^2 whose graph is a parabola with vertex (1, 1) opening upward Graphing we obtain Thus to one decimal place, the two solutions are approximately (06, 36) and (16, 14) Another technique for solving such a system is the method of substitutionHow do you solve the system #5x10y=15# and #3x2y=3# by multiplication?

Put the value of x in any of the equation xy=1 ; Which of the following pairs of linear equations has unique solution, no solution, or infinitely many solutions In case there is a unique solution, find it by using cross multiplication method (i) x – 3y – 3 = 0 3x – 9y – 2 = 0 (ii) 2x y = 5 3x 2y = 8 (iii) 3x – 5y = 6x – 10y = 40 (iv) x – 3y – 7 = 0 3x – 3y – 15SOLUTION 1 Solve by elimination method 4x y = 3 y 3 = 4x 2 Solve by graphing method x y = 3 x y = 1 3 Solve by addition method 2 Solve by graphing method x y = 3 x y = 1 To graph it easily, we will rewrite the equation in slope intercept form 1/5x 2/3y = 8/5 eq1 3x y = 9 eq2 Simplify eq1 Mutiply LCD 15 each
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 Given 1color(white)("XXX")xy=10 2color(white)("XXX")xy=2 Add 1 and 2 3color(white)("XXX")2x=12 rarr4color(white)("XXX")x=6 Subtract 2 from 1Click here👆to get an answer to your question ️ Solve the following by elimination method 2x y = 6 and x 2y = 2 Join / Login biology3x y = 7 Solution 2x – y = 3 (1) 3x y = 7 (2) The coefficient of y in the 1st and 2nd equation are same (1) (2) 2x – y = 3 3x y = 7 5x = 10 x = 10/5 = 2 By applying the value of x in (1), we get 2(2) y = 3
