Can some one please help. 

The symbols \(\triangle\),\(\square\),\(\diamond\),\(\clubsuit\) represent four different integers from 1 to 9. Using the equations below, what is the value of \(\square\) ?

\(\begin{align*} \triangle + \square &= \clubsuit \\ \triangle + \triangle &= \diamond +\diamond + \diamond + \diamond + \diamond \\ \triangle + \triangle &= \clubsuit + \diamond. \end{align*}\)

triangle = 5      diamond = 2     (from second equation)

 

so club = 8    from third equation

 

first eqaution then is   5 + square = 8           square = 3
