Question

$3x + 4y = -3$
$x + 2y = -1$

Explanation:

Step1: Isolate x from second equation

$x = -1 - 2y$

Step2: Substitute x into first equation

$3(-1 - 2y) + 4y = -3$

Step3: Simplify to solve for y

$ -3 - 6y + 4y = -3 \\
-3 - 2y = -3 \\
-2y = 0 \\
y = 0$

Step4: Substitute y=0 into x expression

$x = -1 - 2(0) = -1$

Answer:

$x=-1$, $y=0$
