Three times a number minus 9 is equal to two times the number plus 7

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
