d=-16/5 is the right answer. First, you had to multiply by 100 from both sides of the equation. And it gave us [tex]-5.7*100+2.6d*100=-14.02*100[/tex]. Then, you had to refine. And it gave us [tex]-570+260d=-1402[/tex]. Third, you can also add by 570 from both sides of the equation, and it gave us[tex]-570+260d+570=-1402+570[/tex]. Then simplify and it gave us, [tex]260d=-832[/tex]. Next, you had to divide by 260 from both sides of equation. And it gave us, [tex]\frac{260d}{260}= \frac{-832}{160}[/tex]. And finally, simplify it's should be the right answer. And it gave us the answer is d=-16/5 is the right answer. Hope this helps! Thank you for posting your question at here on brainly. And have a great day! -Charlie
