solve the equation using mental math n divide 9=9

Answer:

81

Step-by-step explanation:

When dividing these numbers, you would actually multiply them together because they are on different sides of the equals sign. You do this because whatever you do on one side, you'd do the opposite of to the other side.

Example:

2x + 3 = 9

You would subtract 3 from nine.

2x = 6

The you'd divide 6 by two, since you would multiply x by two.

x = 3
