Question

Subtract the following expressions: 5a + 3y - 6c and 2a - 4y - 130

Answer 1

I think the answer is 3a-y-6c-130.

Explanation:

You have to collect the like terms.

So, 5a and -2a are both like terms and when you do that you get 3a.

After that the problem is 3a+3y-6c-4y-130.

Then, you do +3y and -4y and you get -y.

After that the problem is 3a-y-6c-130.

So your answer is 3a-y-6c-130.
