Question

7 (x+2/3)+1/3=4(x+1/3)= расписать как уровнение срочно

Answer 1

$7(x + \frac{2}{3} ) + \frac{1}{3} = 4(x + \frac{1}{3} ) \\ 7x + \frac{14}{3} + \frac{1}{3} = 4x + \frac{4}{3} \\ 7x - 4x = \frac{4}{3 } - \frac{15}{3} \\ 3x = - \frac{11}{3} \\ x = - \frac{11}{3} \div 3 \\ x = - \frac{11}{9} \\ x = - 1 \frac{2}{9}$
