Question

Найдите значение выражения 2x-5x, если x=-1 1/3

Answer 1

$2x - 5x = |x = - 1 \frac{1}{3} = - \frac{4}{3} | = 2 \times ( - \frac{4}{3} ) - 5 \times ( - \frac{4}{3} ) = - \frac{8}{3} + \frac{20}{3} = \frac{12}{3} = 4$

Answer 2

2x-5x | при $x=-1\frac{1}{3}=-\frac{4}{3}$

$2*(-\frac{4}{3} )-5*(-\frac{4}{3} )=-\frac{8}{3} +\frac{20}{3} =4$
