Question

решите уравнение x+12/9 - x-1/6 =x+1/3

Answer 1

$\displaystyle\bf\\\frac{x+12}{9} -\frac{x-1}{6} =\frac{x+1}{3} \\\\\\\frac{x+12}{9}\cdot 18 -\frac{x-1}{6}\cdot 18 =\frac{x+1}{3} \cdot 18\\\\\\(x+12)\cdot 2-(x-1)\cdot 3=(x+1)\cdot 6\\\\\\2x+24-3x+3=6x+6\\\\\\-x+27=6x+6\\\\\\-x-6x=6-27\\\\\\-7x=-21\\\\\\x=-21:(-7)\\\\\\\boxed{x=3}$
