Answer:

n=1

Explanation:

3 more than 2 times a number can be represented by: 3+2n (with n representing "number")

equal to that number plus 4 can be represented by: = n+4

put it together and solve:

3+2n=n+4

-3 -3

2n=n+1

-n -n

n = 1

We can check to confirm:

3+2(1) = 1+4

5=5 which is correct
