Question

Решить уравнение 5/3+1/6x=0,75

Answer 1

$\frac{5}{3} + \frac{1}{6} x= \frac{75}{100} \\ \\ \frac{5}{3} + \frac{1}{6} x= \frac{3}{4} /*12 \\ \\ 12* \frac{5}{3} +12* \frac{1}{6} x=12* \frac{3}{4} \\ \\ \frac{12*5}{3} + \frac{12x}{6} = \frac{12*3}{4} \\ \\ 4*5+2x=3*3 \\ 20+2x=9 \\ 2x=9-20 \\ 2x=-11 \\ x=-5.5$
