Let's pick some letters to stand for unknowns; I'll use "s" for the number of spoons and "f" for the number of forks.
In total, there are twice as many spoons as forks, so the number of spoons "s" is twice the number of forks "f". Translate "(spoons) is (twice)(forks)" into an equation.
If we add nine forks, then this will be twice as many forks as spoons. Translate "(forks) plus (another nine) is (twice)(spoons)" into an equation.
Then solve the system of equations!
