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

  • Math - ,

    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.
