    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
