This is the answer. I just wrote and took a pic. of it because it is hard to type it here. haha.
2 3 2
14 - 4 = 10, not 12 (for no. 2: 4 - 5y = 14) and 4 + 12 = 16 (your checking for no. 2)
Hi CrizzyAnne, typo error in Number 2, should be 14-4 = 10.  Therefore divide 10 by -5, then y = -2.  but of course you know how to solve it sans the typo error.  For the inquire's reference.
**inquirer's ...
oh, I am sorry. :(. but thanks for correcting me! :)
You're correct n your solution sans the typo error in Number 2 :-)

2d + 22 = -2\\2d = -2 - 22\\ \frac{2d}{2} = \frac{-24}{2} \\d=-12

4 - 5y = 14\\5y = 14-4\\ \frac{-5y}{-5} = \frac{10}{-5} \\y=-2

33b+5=71\\33b=71-5\\ \frac{33b}{33} = \frac{66}{33} \\b=2

1) d = -12
2) y = -2
3) b = 2
