Answer:
n=16
Step-by-step explanation:
Make an equation
Three times a number minus 9–> 3n-9
Times means multiply, and minus means subtract
Equals two times the number plus 7–> =2n+7
Times means multiply, and plus means add
3n-9=2n+7
Solve for n, by getting n by itself
Subtract 2n from both sides
3n-2n-9=2n-2n+7
n-9=7
Add 9 to both sides
n-9+9=7+9
n=16
