Question

x - 2y = 1\
y = x + 2

Explanation:

Step1: Substitute $y$ into first equation

Substitute $y = x + 2$ into $x - 2y = 1$:
$x - 2(x + 2) = 1$

Step2: Simplify and solve for $x$

Expand and combine like terms:
$x - 2x - 4 = 1$
$-x - 4 = 1$
$-x = 1 + 4$
$-x = 5$
$x = -5$

Step3: Substitute $x$ to find $y$

Plug $x = -5$ into $y = x + 2$:
$y = -5 + 2$
$y = -3$

Answer:

$x = -5$, $y = -3$
