How do you solve this 2 step equation: 9+9n=9

Step 1: Move all terms not containing n to the right side of the equation.

Since 9 does not contain the variable to solve for, move it to the right side of the equation by subtracting 9 from both sides.

9n = - 9+9

9n=-9+9

Add - 9 and 9 to get 0.

9n=0

Step 2: Divide each term by 9 and simplify.

Divide each term in 9n = 0 by 9

9n=0 by 9.

9n / 9 = 0/9

Step 3: Reduce the expression by canceling the common factors.

n = 0/9

Divide 0 by 9 to get 0.

n = 0

Move 9 over to the other side so your equation looks like this:

9n = 9 - 9

Then simplify

9n = 0

n = 0
