-2
Step-by-step explanation:
Hello from MrBillDoesMath!
Answer: b
Discussion:
7b + 3 - 4b = 3 - 3(b+4) =>
7b + 3 - 4b = 3 - 3b -12 =>
(7b - 4b) + 3 = -3b - 9 =>
3b + 3 = -3b -9 => Add 9 to both sides
3b + 12 = -3b -9 + 9 =>
3b + 12 = -3b => ( add 3b to both sides)
6b + 12 = 0 => (subtract 12 from both sides)
6b = -12 =>
b = -12/6 = -2
Thank you,

Answer: 16/24
Step-by-step explanation: Find out a common denominator: 8,16,24 and 3,6,9,12,15,18,21,24. Which is 24.
Take 5/8 multiplied by 3 because its the 3rd multiple of 8. Which is 15/24.
Then, take 2/3 and multiply by 8 because its the 8th multiple of 3. This will give you 16/24.
Make sure to multiply both the top and bottom. :D
