4r + 3(r - 2)
Let's focus on the 3(r-2)
In order to distribute this, we multiply 3 to r AND -2 each
After using the distributive property, we get the following
3(r - 2) = 3r - 6
Now, let's go back to the whole equation
4r + 3(r - 2)
= 4r + 3r - 6
Combine like terms
7r - 6
That's your answer.
Have an awesome day! :)
