Using elimination, what value of (y) is obtained by subtracting (x+y=8) from (x+4y=17)?

Answer and explanation

Correct answer: \(y=3\)

Subtracting the second equation from the first gives \((x+4y)-(x+y)=17-8\). Thus, \(3y=9\), so \(y=3\). For example, \(y=4\) cannot satisfy both equations simultaneously. Exam tip: In elimination, subtract every term on both sides carefully to avoid sign errors.
