Jamie thought he had correctly solved the equation that was on the board, but his answer was not the correct one. Here is his work. Explain what Jamie did wrong and what he needed to do differently to solve the equation correctly:
\({{2(a-5)+6a+3}\over{4}}=4.25\)
\(\frac{2a-10+6a+3}{4} = 4.25\)
\(\frac{8a - 7}{4}= 4.25\)
\(2a - 7 = 4.25\)
\(2a = 11.25\)
\(a = 5.625\)
