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

Answer and explanation

Correct answer: \(x=13\)

Given \(x-y=8\) and \(y=5\), substitute \(y=5\) into the first equation: \(x-5=8\). Adding 5 to both sides gives \(x=13\). For example, \(x=12\) gives \(12-5=7\), not 8. Exam tip: after substitution, carefully use inverse operations to isolate the unknown.
