David and Joseph have a total of 328 marbles Matthew and David have 176 marbles Joseph has five times as many marbles does Matthew how many marbles does David have?

Let,

David has X marbles

Matthew has Y marbles

Joseph has 5 times of Matthew so, 5Y marbles

Here,

X+5y=328 ... (1)

X+Y=176 ... (2)

From (1) - (2),

4Y=152

or, Y=38

By putting Y=38 in (2),

X+38=176

or, X=138

So David has 138

Matthew has 38

and Joseph has 5*38=190 marbles ...
