Simplify them until they can be simplified no more, then compare both sides.
Answer:
6 tablespoons
Step-by-step explanation:
It's more logical because tubes of toothpaste do not require such a large amount of toothpaste. Look at your toothpaste tube. I'm sure that it is closer to 6 tablespoons rather than 6 cups.
First you cross multiply.
2*(b-4)=6b
Then distribute the 2.
2b-8=6b
Minus 2b from each side.
-8=4b
Divide each side by 4.
-2=b
So -2 is your answer.

For number one you do 15-9 which is 6 and that’s the answer
For number to do 25-18 which is 7 and that’s the answer for that one
