This question cannot be answered. I'll set up an equation and then you'll see how 9m + 15w = 25 39m + 10w = ? Now, as you can see there are a infinetely different possibilities for 9m + 15w to equal 25 if m is assumed to equal 1 then w=(25-9)/15; if m is assumed to equal 2, then w=(25-18)15 m could be 1.1 or 1.5 or 0.57 with ongoing infinite possibilities. There aren't enough numbers given..... and we can't use the 35m + 10w because we don't know what that's equal to so those numbers are worthless. You're trying to find 2 different variables with only one equation. That's not going to happen Hope that helps :)

good
