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

Answer:16

Step-by-step explanation:

After writing it out, the equation should be 3n-9=2n+7. Put the variables on one side and the numbers on the other so it should look like 3n-2n=7+9 and the answer is n=16
