Question

1/2(1/3x-1/4)=2x-1 1/2

Answer 1

$frac{1}{2} ( frac{1}{3} x - frac{1}{4} ) = 2x - 1 frac{1}{2} \ \ frac{1}{6} x - frac{1}{8} = 2x - 1.5 \ \ frac{1}{6} x - 2x = - 1.5 + 0.125 \ \ - 1 frac{5}{6} x = - 1.375 \ \ x = frac{1375 times 6}{1000 times 11} \ \ x = frac{3 }{4 } \ \ x = 0.75$

Ответ: 0.75
