Answer:

x=131/21

y=-23/21

Step-by-step explanation:

Given:

5x+2y=29

8x-y=51

Eliminate y variable and solve for x:

  5x+2y=29

+ 16x-2y=102

_________

        21x=131

           x=131/21

Plug x into either original equation and solve for y:

5x+2y=29

5(131/21)+2y=29

655/21+2y=29

655/21+2y=609/21

2y=-46/21

y=-46/42

y=-23/21
