1 answer

Let's call the number we're trying to solve for "x".

According to the problem, the sum of a number (x) and 8 is 180.

So, the equation can be written as: 9(x + 8) = 180.

Now let's solve for x:

9(x + 8) = 180
Divide both sides of the equation by 9:
x + 8 = 20
Subtract 8 from both sides of the equation:
x = 20 - 8
x = 12

Therefore, the number is 12.
