Реши уравнение:

Answer 1

Ответ:

-0,75

Пошаговое объяснение:

$\displaystyle\bf\\\frac{1,3-x}{|3,7-5|-|7,2-11,1|} =\frac{x}{3:3\dfrac{2}{13} } \\\\\\\frac{1,3-x}{|-1,3|-|-3,9|} =\frac{x}{3:\dfrac{41}{13} }\\\\\\\frac{1,3-x}{1,3-3,9} =\frac{x}{3\cdot\dfrac{13}{41} }\\\\\\\frac{1,3-x}{-2,6} =\frac{41x}{39 }~~~~~~~~~~|\cdot39\\\\\\\frac{39(x-1,3)}{2,6} =41x\\\\15(x-1,3)=41x\\\\15x-19,5=41x\\\\-19,5=41x-15x\\\\-19,5=26x\\\\x=-19,5:26\\\\x=-0,75$
