Answer:

x= -1 and y =7

Step-by-step explanation:

To solve by elimination, multiply the entire first equation by 2 so that your x terms have the same coefficients.

2*(9x+2y=5) becomes 18x+4y=10.

Now stack and add each like term.

18x+4y=10

-18x-3y=-3

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

0x +y = 7

y=7

Substitute y=7 into one of the original equations and solve for x.

9x +2(7) = 5

9x + 14 = 5

9x = -9

x=-1
