Let's start by defining our unknown number.
Let's call it x.
Now, Let's handle the first part of it. 3 more than five times a number. That can be represented by the following
![3+5x](https://img.qammunity.org/2019/formulas/mathematics/middle-school/a4j71cf9yy8kj14p3mborm64oz6rq6x2js.png)
Now we handle the second part, "Thirty more than twice the number"
Which can be represented by
![30+2x](https://img.qammunity.org/2019/formulas/mathematics/middle-school/1wckcdgu6tiwygt01bbotbk7a7joksnfcv.png)
So, now we set them equal, since it tells us that these expressions are the same. Then we just solve the equation
![3+5x=30+2x\\\\5x=27+2x\\\\3x=27\\\\x=9](https://img.qammunity.org/2019/formulas/mathematics/middle-school/cf5nuuvydsu55xvpu4virjwl8upm9fn5vw.png)
The answer is 9
