Good Afternoon, So were going to make the formula the simplest we can so see what i do ;)
[]70/x=100/8.5
<span>[](70/x)*x=(100/8.5)*x - If you notice, </span>we multiply both sides of the equation by x <span> []70=11.764705882353*x - Here, </span>we divide both sides of the equation by (11.764705882353) to get x <span> []70/11.764705882353=x </span> <span> []5.95=x </span> <span> []x=5.95 </span> I hope i helped, and good luck on your studying ^.^
