-4x-2y=-12 4x+8y=-24

Answers

Answer:

x=6\n \ny=-6

Step-by-step explanation:

Given the system of two equations:

\left\{\begin{array}{l}-4x-2y=-12\n \n4x+8y=-24\end{array}\right.

Add these two equations (left side add to left side and right side add to right side):

-4x-2y+4x+8y=-12+(-24)\n \n-2y+8y=-12-24\n \n6y=-36\n \ny=-6

Substitute y=-6 into the first equation:

-4x-2\cdot (-6)=-12\n \n-4x+12=-12\n \n-4x=-12-12\n \n-4x=-24\n \nx=6
