Question

Three consecutive integers have a sum of 87. Find the integers.

Answer 1

28, 29, 30

Explanation:

Let the first integer = x

Let the second integer = x + 1

Let the third integer = x + 2

x + x + 1 + x + 2 = 87 Combine like terms

3x + 3 = 87 Subtract 3 from both sides

3x = 84 Divide both sides by 3

3x = 84 Divide both sides by 3

x = 29

Check:

28 + 29 + 30 = 87

87=87
