Question

найдите корень уравнения 1) 2/3 (1/3x-1/2)=4x+2 1/2

Answer 1

$\frac{2}{3}( \frac{1}{3}x- \frac{1}{2})=4x+2 \frac{1}{2}$
$\frac{2}{9}x- \frac{1}{3}=4x+2 \frac{1}{2}$
$\frac{2}{9}x-4x=2 \frac{1}{2}+ \frac{1}{3}$
$- \frac{34}{9}x= \frac{17}{6}$
$x= - \frac{17}{6}: \frac{34}{9}$
x=$- \frac{3}{4}$
