The property used to arrive at Step 1: Distributive Property (The student distributed the 2 across the terms in parentheses: 2(x + 1) = 2x + 2).
-
The step that includes a mistake made from the previous step: Step 4 (The student incorrectly divided 15 by 3 to obtain x = 45, when the correct calculation should yield x = 5).
-
The correct answer for x: x = 5.
A student solved the equation: x+2(x+1)=17
Step 1: x+2x+2=17
Step 2: 3x+2=17
Step 3: 3x=15
Step 4: x=45
