Solve for \(x\), if \(4(x+1)-3(2x-1)=x+7\)
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 0
This is a linear equation in one variable: expand the brackets, collect the \(x\) terms on one side and the numbers on the other. Watch the sign when the bracket after −3 is expanded: \(-3\times(-1)=+3\).
Left side after expanding: \(4x+4-6x+3=7-2x\)
The equation becomes \(7-2x=x+7\), so \(3x=0\) and \(x=0\)
