Question

What is a detailed answer to 11(3k+7–2k)–4 ????

Answer 1

`11k+73`

Explanation:

`11(3k+7-2k)-4`

Firstly, we expand the bracket,

`33k+77-22k-4`

Now, we collect like terms,

`33k-22k+77-4=11k+73`

As this is not equal to anything, we cannot solve for k.

So simplification is all we can do here.
