Select all the equations that have 8 as a solution.

• y - 9 = -1

• b - 5 = 3

• 4a = 32

• 80 ÷ x = 8

• 3p = 20

Answer explanation

Solution = value of the variable/letter that makes the equation true.

Replace the letter with the value and check if the left and right side are equal.

A) y - 9 = -1

8 - 9 = - 1 ✅

• B) b - 5 = 3

• 8 - 5 = 3 ✅

• C) 4a = 32

• 4 (8) = 32 ✅

• D) 80 ÷ x = 8

• 80 ÷ 8 = 8 (this is wrong since 80 ÷ 8 is 10)

E) 3p = 20

3(8) = 20 (this is wrong since 3(8) is 24)
