Question

10/40
3x + y = 4
x + 2y = -2

Explanation:

Step1: Isolate y from first equation

$y = 4 - 3x$

Step2: Substitute y into second equation

$x + 2(4 - 3x) = -2$

Step3: Simplify to solve for x

$x + 8 - 6x = -2 \\
-5x = -10 \\
x = 2$

Step4: Substitute x back to find y

$y = 4 - 3(2) = 4 - 6 = -2$

Answer:

$x=2$, $y=-2$
