If (2x-y=8) and (x=5), what is the value of (y)?

Answer and explanation

Correct answer: \(y=2\)

Given \(x=5\), substitute it into \(2x-y=8\): \(2(5)-y=8\), so \(10-y=8\). Subtracting 10 from both sides gives \(-y=-2\), hence \(y=2\). For example, if \(y=3\), the left side becomes \(10-3=7\), not 8. Exam tip: verify the obtained value by substituting it back into the original equation.
