Answer 1

1.-  5x - 2y = 13

 (x  +  3y = 6 )-5 = -5x -15y = -30

5x - 2y = 13

-5x -15y = -30

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

 0 -17y = -17

  y = -17/-17 = 1

    5x - 2(1) = 13

      5x = 13 +2

        x = 15/5 = 3

2.-  ( 4x - 3y = 10 ) 2 = 8x -6y = 20

      5x + 6y = -7

 5x + 6y = -7

 8x -6y = 20

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

13x + 0 = 13

  x = 13/13 = 1

5(1) + 6y = -7

6y = -7-5

 y = -12/6 = -2
