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
[tex]3+5x[/tex]
Now we handle the second part, "Thirty more than twice the number"
Which can be represented by
[tex]30+2x[/tex]
So, now we set them equal, since it tells us that these expressions are the same. Then we just solve the equation
[tex]3+5x=30+2x\\\\5x=27+2x\\\\3x=27\\\\x=9[/tex]
The answer is 9
