Jason can check his answer by substituting \( x = 6.5 \) back into the original equation:
\[ -8.5(6.5) - 3.5(6.5) = -78 \]
Calculating the left side:
\[ -55.25 - 22.75 = -78 \]
Since both sides equal \(-78\), Jason's solution is verified.
Jason solved the following equation to find the value for x.
–8.5x – 3.5x = –78
x = 6.5
