Question

5x+2y=16,3x-4y=16 solve by elimination method​

Answer 1

Answer:

x = 46/13

y = -11/13

Step-by-step explanation:

5x + 2y = 16 ---------1

3x - 4y = 16 ---------2

doing (eq 1) x 2 + (eq 2)

( so that y terms become opposites)

10x + 4y = 32

3x - 4y = 14

--------------------

13x = 46

x = 46/13

putting the value of x in eq 1, we get,

2y = 16 - 5x(46/13)

2y = 16 - 230/13

2y = -22/13

y = -11/13
