From the first line, we know that  equals 10, because 10 + 10 + 10 = 30.

From the second line, we know that equals 5, because 10 + 5 + 5 = 20.

From the third line, we know that  equals 2, because 5 + 2 + 2 = 9.

In the forth line, we have 2 unknown, both the questionmark and the .

The have a lot of similarities with   witch equals 2.

We could assume that is half of , and therefore  equals 1.
Then the last line would give 15, because 5 + 1 x 10 = 15. “always multiply before adding”
But we don’t really know, maybe is larger than half of , and therefore equals 1,5, or smaller and only equals 0,5?
Maybe is from another three than , and therefore equals 9?

The equation is unsolveable.
