let no. of books Jose have=x
then, Mary has 3x - 4books
so... 3x-4+x=16
3x+x=16+4
4x=20
x=20÷4
x=5
So.. Jose has 5 books
then, Mary has 3x - 4books
so... 3x-4+x=16
3x+x=16+4
4x=20
x=20÷4
x=5
So.. Jose has 5 books

Let Jose brought 'w' books.
So,
No. of books Mary brought = 3w - 4
Therefore,
Total no. of books = 16
=> (3w - 4) + w = 16
4w = 20
w = 5
so, Jose brought 5 books.
So,
No. of books Mary brought = 3w - 4
Therefore,
Total no. of books = 16
=> (3w - 4) + w = 16
4w = 20
w = 5
so, Jose brought 5 books.
