The two equations 74 + 13 = 87 and 87 - 13 = 74 demonstrate the inverse relationship between addition and subtraction. In the first equation, adding 13 to 74 gives you 87, while in the second equation, subtracting 13 from 87 returns you to 74. This showcases how addition and subtraction are inverse operations, with subtraction "undoing" the action of addition.
