Solve (2x+y=16) and (x-y=2) by substitution.

Answer and explanation

Correct answer: \((6,4)\)

From the second equation, \(x-y=2\), we get \(y=x-2\). Substituting this into \(2x+y=16\) gives \(2x+(x-2)=16\), so \(3x=18\) and hence \(x=6\). Then \(y=x-2=4\). Therefore, the solution is \((6,4)\). For \((5,6)\), \(x-y=-1\), so it does not satisfy the second equation. Exam tip: verify the ordered pair in both original equations.
