A student solved the equation: x+2(x+1)=17
Line 1: x+2x+1=17
Line 2: 3x+1=17
Line 3: 3x=16
Line 4: x=16/3
Identify the Property used to go from Line 2 to Line 3: [ ]
Which line has a mistake? [ ]
What should have been the correct answer for the equation? [ ]
The property used to go from Line 2 to Line 3 is the addition property of equality, which states that if the same quantity is added to both sides of an equation, the equality is maintained.
No lines have a mistake.
The correct answer for the equation is x = 16/3.
