Question
A student provided the steps for solving an equation. Which statement describes the error in the
solution?
In step 3, the Addition Property of Equality was
applied incorrectly.
Equation: 8-= 3(4- Sa)
In step 2, the Distributive Property was applied
incorrectly.
16-a = 6(4-5a) (step 1)
(step 2)
(step 3)
(step 4)
(step 5)
Solution:
16-a = 24-5a
16+4a = 24
In step 5, the Multiplication Property of Equality was
applied incorrectly.
4a = 8
a = 2
In step 1, the Multiplication Property of Equality was
