$$2x-8 \times \frac{ 11 }{ 28 } =7$$
$x = \frac{71}{14} = 5\frac{1}{14} \approx 5.071428571$
$$2x-\frac{8\times 11}{28}=7$$
$$2x-\frac{88}{28}=7$$
$$2x-\frac{22}{7}=7$$
$$2x=7+\frac{22}{7}$$
$$2x=\frac{49}{7}+\frac{22}{7}$$
$$2x=\frac{49+22}{7}$$
$$2x=\frac{71}{7}$$
$$x=\frac{\frac{71}{7}}{2}$$
$$x=\frac{71}{7\times 2}$$
$$x=\frac{71}{14}$$
