Solve the equation: n + 32 = 60.
Digiron [165]
N + 32 = 60

First, so basically, we are trying to find a number that can add up with 32 to equal 60. The easiest route to solve this is to simply take 32 and subtract it from 60.
n = 60 - 32

Second, once we subtract, we will be given the answer and know what 'n' is. Subtract 60 - 32 to get your answer. 60 - 32 = 28
n = 28

Third, know that we know that the answer to 'n' is 28, we can check it by adding 28 + 32. Your answer should be 60, and 28 is the correct answer.

Answer: \fbox {n = 28}
