Question

5/6*(1/3 * x - 1/5) = 3x + 3 1/3 допоможіть срочно ​

Answer 1

Объяснение:

$\frac{5}{6} \times ( \frac{1}{3} \times x - \frac{1}{5} ) = 3x + 3 \frac{1}{3} \\ \frac{5}{18} x - \frac{1}{6} = 3x + \frac{10}{3} \\ 5x - 3 = 54x + 60 \\ 5x - 54x = 60 + 3 \\ - 49x = 60 + 3 \\ - 49 = 63 \\ x = - \frac{9}{7} = - 1 \frac{2}{7}$
