How do you solve for d?
16d  (4  5d) = 67
How do you solve for m?
2/7(4m  18) = 12
How do you solve for b?
1/4(5b + 11) = 19
How do you solve for x?
5/6(9 + 2x) = 40

16d  (4  5d) = 67
16d + 5d = 67 + 4
21d = 63
d = 3
~~~~~~~~~~~~~~~~~~~~~~~~~~~
2/7(4m  18) = 12
8m  36 = 84
8m = 120
m = 15
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Now that I've shown you how to do these, you can do the other two. I'll be glad to check your answers.
