Question

1. $-5x + y = -2$

$-3x + 6y = -12$

Explanation:

Step1: Isolate y in first equation

$y = 5x - 2$

Step2: Substitute y into second equation

$-3x + 6(5x - 2) = -12$

Step3: Simplify and solve for x

$-3x + 30x - 12 = -12$
$27x = 0$
$x = 0$

Step4: Substitute x=0 into y=5x-2

$y = 5(0) - 2 = -2$

Answer:

$x=0$, $y=-2$
