Answer
$\{(6,2)\}$
Work Step by Step
1. The second equation has 1 as a coefficient of $x$. Solve it for x.
$x=y+4$
2. Substitute $x$ in the other equation and solve.
$4y=2(y+4)-4$
$4y=2y+8-4\qquad/-2y$
$2y=4\qquad/\div 2$
$y=2$
3. Back-substitute into the expression of $x$ (step 1).
$x=(2)+4=6$
4. Write the solution as an ordered pair.
Solution set: $\{(6,2)\}$
