Question

решите уравнение :
( 5 целых 1/6 -x) * 2,7 - 1 целая 3/14 = 3 целых 2 /7

Answer 1

$(5 \frac{1}{6}-x)\cdot 2,7-1 \frac{3}{14}=3 \frac{2}{7} \\ \\ (5 \frac{1}{6}-x)\cdot 2,7=1 \frac{3}{14}+3 \frac{4}{14} \\ \\ (5 \frac{1}{6}-x)\cdot 2,7=4 \frac{7}{14}$
$(5 \frac{1}{6}-x)\cdot 2,7=4,5 \\ \\ (5 \frac{1}{6}-x)=4,5:2,7 \\ \\ (5 \frac{1}{6}-x)=1 \frac{2}{3} \\ \\ x=4 \frac{7}{6}-1 \frac{4}{6} \\ \\ x=3 \frac{3}{6} \\ \\ x=3 \frac{1}{2} \\ \\ x=3,5$
