I think the walls colours of my classroom are too ugly. So I bought 2 orange paint pots and 1 green paint pots for a global price of £91.
A friend did the same but he bought 3 orange paint pots and 4 green paint pots for a global price of £204.
We lost the bill and we want to know orange and green paint pots prices.
The orange paint pot price is noted x.
The green paint pot price is noted y.
S {2x + 1y = 91
{3x + 4y = 204
Now my classroom is the most beautiful of the worl
