If helmet + helmet - helmet = 30, then 30 + 30 - 30 = 30, so helmet = 30

If quiver + quiver + helmet = 130, then 50 + 50 + 30 = 130, so quiver = 50

If quiver - double axe - helmet = 10, then 50 - 10 - 30 = 10, so double axe = 10

Therefore helmet + quiver x single axe = ? 

If double axe = 10, then single axe = 5

30 + 50 x 5 = 400, so ? = 400

400 is the solution to the puzzle, therefore 400 = 2000 sapphires

I wanted to do this, you know?

Seeing as I solved it the exact same way. Although I am lazy enough to just quote this and say "Yep, that's my answer too. The solution is 400."

230  ;)

Answer is.....280 in algebraic equations to simplify all multiplication and division is done first.

30+30-30=30

50+50+30=130

50-10-30=10

30+50*5=?

30+(50*5)=
