If C + D = 17 and C and D are positive integers, which of the following is a possible value for 3C + 2D?
Choose the correct choice from the following options:
A) 29
B) -29
C) 0
D) -19
E) 19
c + d = 11   3c + 2d = 2c + c + 2=

<output>2</output>
2(c+d) + c= 34+ c=c=-34   Now this reults in   c+d=17=-34+d=17=d=51   c=-34;d=51   3c + 2d=3(-34)+2(51)=-102+102=

<output>0</output>
0   3c + 2d= 0   Hence, 0 is the right answer.
<result>C</result>
