解方程
$\frac{5}{x} + 7 ÷ \frac{3}{7}$= 37
已知: $\frac{5}{x} + 7 ÷ \frac{3}{7}$
要求: 求$x$的值
答案
$\frac{5}{x} + 7 ÷ \frac{3}{7}$= 37
=>$\frac{5}{x} + 7 \times \frac{7}{3}$= 37
=>$\frac{5}{x} + \frac{49}{3}$=37
=> $\frac{5}{x} = 37 - \frac{49}{3}$
=> $\frac{5}{x} = \frac{111 - 49}{3}$
$\frac{5}{x}$ = $\frac{62}{3}$
$x$ = $5 \times \frac{3}{62}$ =$\frac{15}{62}$
因此,$x$的值为$\frac{15}{62}$
