Question

6b plus 7b-10=
Would I add 6b + 7b=13b-10
13b-10=3b?

Would this be correct? Please advise.

Answer 1

No.

You can't combine a term with an unknown with a term without an unknown.

6b plus 7b-10= 13b - 10

Answer 2

So would it just be 13b-10?

Answer 3

Yep.

Let's suppose that b = 3. 13b = 39
13b - 10 = 29

What would the answer be if b = 2?

Answer 4

I am sorry Ms. Sue I do not understand this.

Answer 5

You already posted the answer. What don't you understand?

Answer 6

b is an unknown number
