Question

Solve by elimination method 5x-2y=11, 3x+4y=4.​

Answer 1

Answer:

x = 2  y= -1/2

Step-by-step explanation:

5x-2y=11   {1} . 2

3x+4y=4    {2} . 1

-> 10x-4y=22

+     3x+4y = 4    

-> 13x = 26

-> x= 26/13 x= 2/1 x= 2

-> 3(2)+4y=4

->6+4y=4 -> 4y= 4-6

-> 4y= -2 -> y= -2/4 -> y=-1/2
