Question

5x+2y=7
-2x+6y=9

Answer 1

are the two equations part of the same problem or separate?

Answer 2

Same

Answer 3

alright so multiply each of the top numbers by -3 so that your y equals 0 and then you can find x

Answer 4

Multiply the first equation by 3, then subtract:

15x + 6y = 21
-2x + 6y = 9

17x = 12

x = 12/17

Solve for y

Answer 5

\[(5x+2y=7)-3\]\[-15x-6y=-21\]\[-2x+6y=9\]\[-17x=-12\]
x=12/17
