Answer 1

Answer:

Step-by-step explanation:

3x-4y=10 (mutiplying by 3)

4x+3y=5 (multiplying by 4)

we get:- 9x-12y=30

              16x+12y=20

     now adding both the equations

       we get      25x=50

                       so, x=5

   putting the value x=2 in any equation we get

     y= -1
