Question

cuanto es 1/3(9/2 x -- 6/5) =1/2?

Answer 1

Explicación paso a paso:

$\frac{1}{3} ( \frac{9}{2} x - - \frac{6}{5} ) = \frac{1}{2} \\ \\ \frac{1}{3} ( \frac{9}{2}x + \frac{6}{5} ) = \frac{1}{2} \\ \\ \frac{9}{6} x + \frac{6}{15} = \frac{1}{2} \\ \\ \frac{3}{2} x + \frac{2}{5} = \frac{1}{2} \\ \\ \frac{3}{2} x = \frac{1}{2} - \frac{2}{5} \\ \\ \frac{3}{2} x = \frac{5 - 4}{10} \\ \\ \frac{3}{2} x = \frac{1}{10} \\ \\ x = \frac{1}{10} \div \frac{3}{2} \\ \\ x = \frac{2}{30} \\ \\ x = \frac{1}{15} \\ \\ comprobacion \\ \frac{1}{3} ( \frac{9}{2} \times \frac{1}{15} - - \frac{6}{5} ) = \frac{1}{2} \\ \\ \frac{1}{3} ( \frac{9}{30} + \frac{6}{5} ) = \frac{1}{2} \\ \\ \frac{1}{3} ( \frac{3}{10} + \frac{6}{5} ) = \frac{1}{2} \\ \\ \frac{1}{3} ( \frac{3 + 12}{10}) = \frac{1}{2} \\ \\ \frac{1}{3} \times \frac{15}{10} = \frac{1}{2} \\ \\ \frac{1}{3} \times \frac{3}{2} = \frac{1}{2} \\ \\ \frac{3}{6} = \frac{1}{2} \\ \\ \frac{1}{2} = \frac{1}{2}$
