Question

Enter the y-coordinate of the solution. Round to the nearest tenth. 5x+2y=7 -2x+6y=9

Answer 1

59/34

Explanation:

5x+2y=7

-2x+6y=9

Multiply the top equation by 3:

15x+6y=21

Subtract the second equation from the first:

17x=12

x=12/17

Plug this back into one of the other equations to find y:

5(12/17)+2y=7

60/17+2y=7

2y=59/17

y=59/34

Hope this helps!
