In the equations (x+3y=23) and (y=6), what is (x)?

Answer and explanation

Correct answer: \(x=5\)

From the second equation, \(y=6\). Substituting it into \(x+3y=23\) gives \(x+3(6)=23\), or \(x+18=23\). Hence, \(x=5\). The close distractor \(x=6\) is incorrect because it makes the left-hand side \(24\), not \(23\). Exam tip: Verify the obtained value by substituting it back into the original equation.
