How Do I Simplify 8R - 4(2R +1) + 4?

8

Step-by-step explanation:

8r - 4(2r + 1) + 4

First, you have to use the distributive property to solve what's inside the parenthesees:

4(2r) + 4(1) = 8r + 4

Now, the problem is:

8r - 8r + 4 + 4

When we subtract 8r - 8r, we get 0. Therefore the variable r is gone since the coefficient is 0.

The problem now is:

4 + 4

We get the answer of 8.
