Question

-3x - y = -13
x + 2y = 6

Explanation:

Step1: Isolate x from second equation

$x = 6 - 2y$

Step2: Substitute x into first equation

$-3(6 - 2y) - y = -13$

Step3: Expand and simplify for y

$-18 + 6y - y = -13$
$5y = 5$
$y = 1$

Step4: Substitute y back to find x

$x = 6 - 2(1)$
$x = 4$

Answer:

$x=4$, $y=1$
