c=3/2 is the final answer. First, you had to divide by two (2) from both sides of equation, and it gave us ⇒ [tex]\frac{2(5c-7)}{2}= \frac{1}{2}[/tex]. And secondly, you had to simplify, and it gave us ⇒[tex]5c-7=\frac{1}{2}[/tex]. Next, you had to add by seven (7) from both sides of equation, and it gave us ⇒[tex]5c-7+7=\frac{1}{2}+7[/tex]. Therefore, you can also simplify, and it gave us ⇒[tex]5c=\frac{15}{2}[/tex]. In fact, you divide by five (5) from both sides of equation, and it gave us ⇒[tex]\frac{5c}{5}= \frac{12}{2/5}[/tex]. And finally, simplify it's should be the final answer is c=3/2 is the final answer. Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie
