Multiply both sides by 2 to eliminate fractions, then subtract 3, giving x = 19, which is the proper adjustment after an initial subtraction error
The student should have added 3 to both sides first to isolate 2x, then taken the square root to find x, yielding x = √14
The student correctly subtracted 2; the next step is to subtract 1 from both sides to get x = 5, which matches the provided arithmetic
The student subtracted 2 instead of 3; correct sequence: subtract 3 from both sides to get 2x = 8, then divide by 2 to get x = 4
