If (x-y=6) and (y=2), what is the value of (x)?

Answer and explanation

Correct answer: 8

Given \(x-y=6\) and \(y=2\). Substituting 2 for \(y\) gives \(x-2=6\). Adding 2 to both sides gives \(x=8\). Therefore, option C is correct. The value 6 is only the right-hand side of the equation, not the value of \(x\). Exam tip: After substitution, apply the same operation to both sides to isolate the variable.
