Answer
$\{(-1,-11)\}$
Work Step by Step
1. The second equation has $y$ already expressed in terms of $x$
$y=11x$
2. Substitute $y$ in the other equation and solve.
$6x-y=5$
$6x-(11x)=5$
$-5x=5\qquad/\div(-5)$
$x=-1$
3. Back-substitute into the expression of $y$ (step 1).
$y=11(-1)=-11$
4. Write the solution as an ordered pair.
Solution set: $\{(-1,-11)\}$
