Quizplus · Accepted Answer

Substitute $x = 1 - 2y$ into the second equation: $1 - 2y + 2y = 8$ simplifies to $1 = 8$, which is a contradiction, indicating no solution.

Solve Using the Substitution Method x=1+−2yx+2y=8\begin{array} { l } x = 1 + - 2 y \\x + 2 y = 8\end{array}x=1+−2yx+2y=8​

Solve Using the Substitution Method $\begin{array} { l } x = 1 + - 2 y \\x + 2 y = 8\end{array}$
