Which statement tells the reasoning you can use to find the unknown number, n, in this equation?

n + 79 = 30 + 74

• Add 5 to 30 because 79 is 5 more than 74.

• Add 30 to 74 because that is the value of the right side.

• Subtract 5 from 30 because 79 is 5 more than 74.

• Subtract 30 from 79 because 79 is 30 more than the value of the right side.
