Which equation should be used to solve this problem?
There is a number that is 8 less than the sum of 20 + 12. Find the number.
Let n = the number.
20 + 12 - 8 = n
To solve this problem, we are given that the number we are looking for is 8 less than the sum of 20 and 12.
Let's express this information using an equation.
The sum of 20 and 12 is written as:
20 + 12 = 32
We are given that the number we are looking for is 8 less than this sum. So we can write:
n = 32 - 8
Simplifying this equation gives us:
n = 24
Therefore, the number we are looking for is 24.
So, the equation that should be used to solve this problem is:
n = 32 - 8.
