Answer:

x = 4, y =5

Step-by-step explanation:

2x+5y=33.

3x-5y=-13

Add the two equations together to eliminate y

2x+5y=33.

3x-5y=-13

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

5x = 20

Divide by 5

5x/5 = 20/5

x = 4

Now find y

2x + 5y = 33

2(4) +5y = 33

8+5y = 33

Subtract 8 from each side

8+5y-8 = 33-8

5y = 25

Divide each side by 5

5y/5 = 25/5

y = 5
