Answer
$x = 1$
$y = 2$
Work Step by Step
$2y - 4 = 0$
$x + 2y = 5$
Therefore
$2y = 4$
$x + 2y = 5$
$a = 0$ , $b = 2$, $c = 1$, $d = 2$, $h = 4$, $k = 5$
lets calculate
$D = ad-bc = 0 - 2 = - 2$
$D_x = hd-bk = 8-10 = - 2$
$D_y = ak-ch= 0-4= - 4$
Therefore by Cramer's rule,
$x = \frac{D_x}{D} = \frac{-2}{-2} = 1$
$y = \frac{D_y}{D} = \frac{-4}{-2} = 2$
