C) 2 (x-1)/3 - 3(x+1)/2 = (x+2)/6

Answer 1

$2\cdot (x-1)/3 - 3\cdot (x+1)/2 = (x+2)/6\\\\2\times \dfrac{x-1}{3}-3\times \dfrac{x+1}{2}=\dfrac{x+2}{6}\\\\\dfrac{2x-2}{3}-\dfrac{3x+3}{2}=\dfrac{x+2}{6}\\\\\dfrac{2(2x-2)-3(3x+3)=x+2}{6}\\\\\\2(2x-2)-3(3x+3)=x+2\\4x-4-9x-9=x+2\\-5x-13=x+2\\-5x-x=2+13\\-6x=15\\x=\dfrac{15}{-6}\\x=-\dfrac{5}{2}\\\boxed{x=-2,5}$
