What is the simplified form of (2(3x-4)-[x-2(1-x)])?

Answer and explanation

Correct answer: \(3x-6\)

First simplify the square bracket: \(x-2(1-x)=x-2+2x=3x-2\). Also, \(2(3x-4)=6x-8\). Therefore, the expression becomes \(6x-8-(3x-2)=6x-8-3x+2=3x-6\). Hence, option A is correct. The result \(3x-10\) can arise if the sign of \(+2\) is handled incorrectly while subtracting \((3x-2)\). Exam tip: when a minus sign occurs before a bracket, change the sign of every term inside it.
