2) -3x + 6y = -12\n-3x + y = 13

Explanation:

Step1: Subtract the second - equation from the first

$(-3x + 6y)-(-3x + y)=-12 - 13$ $-3x+6y + 3x - y=-25$ $5y=-25$

Step2: Solve for y

$y=\frac{-25}{5}=-5$

Step3: Substitute y = - 5 into the second equation

$-3x+( - 5)=13$ $-3x=13 + 5$ $-3x=18$

Step4: Solve for x

$x=\frac{18}{-3}=-6$

Answer:

$x=-6,y = - 5$
