Shows or implies a correct first step of algebraic manipulation that
either reduces the number of terms or collects variables on one
side of the equation and numbers on the other or correctly
removes the brackets, eg:
•
8y + 96 = 100
•
y + 12 = 100 ÷ 8
•
8y = 4
OR
Shows or implies a complete correct method, eg:
•
100 ÷ 8 = 12 (error)

94 ÷ 8 = 11.75
