If each of 12 artists submitted either one or two paintings for an exhibition, and a total of 17 paintings were submitted, how many artists submitted only one painting?
-----------------
artist quantity:: o + t = 12 artists
Paintings quantity:: o + 2t = 17 paintings
---------------------
Subtract and solve for "t":
t = 5
-------
Solve for "o"::
o + t = 12
o + 5 = 12
o = 7 (# of artists submitting only one painting)
