Answer:

(5,-2)

Step-by-step explanation:

9x+5y=35

2x+5y=0

Multiply the second equation by -1

-1 (2x+5y) = 0*-1

-2x-5y = 0

Add the first equation and the modified second equation

9x+5y=35

-2x-5y = 0

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

7x = 35

Divide by 7

7x/7 = 35/7

x = 5

Now we need to find y

2x+5y = 0

Substituting in x

2(5) +5y = 0

10 +5y = 0

Subtract 10

10-10 +5y = -10

5y = -10

Divide by 5

5y/5 = -10/5

y = -2
