10x + 13y = 11....multiply by 3
3x + 14y = -27....multiply by -10
------------------
30x + 39y = 33 (result of multiplying by 3)
-30x - 140y = 270 (result of multiplying by -10)
-------------------add
- 101y = 303
y = 303/-101
y = -3
10x + 13y = 11
10x + 13(-3) = 11
10x - 39 = 11
10x = 11 + 39
10x = 50
x = 50/10
x = 5
solution is : (5,-3)

Step-by-step explanation: The ratio of apples to oranges is 2:5. That means for every 2 apples there will be 5 oranges.
We want to know how many total pieces of fruit will be in the basket where there are 10 apples.
Lets use the ratio to get the total number of fruits when we have 10 apples.
2:5 there is 2 apples when there is 5 oranges;
4:10 there is 4 apples when there is 10 oranges;
6:15 there is 6 apples when there is 15 oranges;
8:20 there is 8 apples when there is 20 oranges;
10:25 there is 10 apples when there is 25 oranges;
Now simply add the total amount of apples and oranges. 10 + 25 = 35 total fruit.
