Problem

The operations \boxdot and \diamond are defined as follows:
  • xy=3y+4x \boxdot y = 3y+4
  • xy=(3x)(y)x \diamond y = (3-x)(y)
Find 3(26)3 \diamond (2 \boxdot 6).
  • Your answer should be
  • an integer, like 6
  • a simplified proper fraction, like 3, slash, 5
  • a simplified improper fraction, like 7, slash, 4
  • a mixed number, like 1, space, 3, slash, 4
  • an exact decimal, like 0, point, 75
  • a multiple of pi, like 12, space, p, i or 2, slash, 3, space, p, i
