Question

(3) 2x - Зу = 9; 2x + y = 13​

Answer 1

Answer:

2x-3y=9........(1)

2x+y=13.........(2)

Multiplying equation (2) by 3 we get,

6x+3y=39.............(3)

Adding Equation (1) and (3) we get

8x=48

x=6 &

y=1

Answer 2

Answer:

the answer is    x = 15/4  ,  y = 11/2  

Step-by-step explanation:

              Eq (1) - Eq (2)

            $2x + y= 13\\2x -3y = 9\\- + = -$    

               4y =4                 so, x=6 , y=1
