Question

find the solution of 2r-(5-r)=13+2r

Answer 1

Distribute the negative then add like terms. (:Those are your first steps. Then you isolate r.

Answer 2

\[
2r-(5-r)=13+2r\\
r-5=13\\
r=18
\]

Answer 3

Step 1. Remove common terms by subtracting 2r from both sides; 2r-(5-r)=13+2r -> -(5-r)=13
Step 2. Distribute the inverse; -(5-r)=13 -> r-5=13
Step 3. Isolate r by adding 5 to both sides. r-5=13 -> r=18
