Expand the brackets first
5(wx-v) = 9(x + v)
5wx - 5v = 9x + 9v
Get all x's on one side and everything on on the other side
9x - 5wx = 9v + 5v
factorise out the x
x(9-5w) = 14v
then divide by 9-5w
x = 14v/(9-5w)

lets say tomatoes = x
3/5 x = 30
divide by 3 on both sides
1/5 x = 10
multiply by 5 on both sides
x=50
