Part A: Based on the information provided, which statement explains why his solution is incorrect?
LeBron attempted to solve the following equation:
1 5 (4x-1) = 2+x
His work is shown below:
Step 1: 4x-1=5+x
Step 2: 3x-1=5
Step 3: 3x = 6
Step 4: x = 2
He forgot to multiply x by 2 in Step 1.
He added x to both sides of the equation in Step 2 instead of subtracting x
He added 1 on both sides of the equation in Step 3 instead of subtracting 1.
He multiplied by the reciprocal of 3 to get x = 2 in Step 4
The correct statement explaining why his solution is incorrect is:
He forgot to multiply x by 2 in Step 1.
