Question

Решите уравнение
(2 2/9 - 5/6x) * 9 + 1/2x = 6

Answer 1

$(2 frac{2}{9} - frac{5}{6x} )*9+ frac{1}{2x} =6 \ ( frac{20}{9} - frac{5}{6x} )*9+ frac{1}{2x} =6 \ 20 - frac{15}{2x} + frac{1}{2x}=6 \ frac{40x}{2x} - frac{15}{2x} + frac{1}{2x}= frac{12x}{2x} \ 40x - 15 + 1 = 12x \ 40x - 12x = 15 - 1 \ 28x = 14 \ x = frac{14}{28} \ x = frac{1}{2}$
