**PsyDAG**, Saturday, November 24, 2012 at 10:55amx = 65 - 2y

2x + 3y = 105

Substitute 65-2y for x in second equation and solve for y. Insert that value into the first equation and solve for x. Check by inserting both values into the second equation.

It definitely is not D! You are right with B.
