Answer:

$x=6\\ \\y=-6$

Step-by-step explanation:

Given the system of two equations:

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

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

$-4x-2y+4x+8y=-12+(-24)\\ \\-2y+8y=-12-24\\ \\6y=-36\\ \\y=-6$

Substitute $y=-6$ into the first equation:

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

1 * 60 * 60 = 3600 (seconds in 1 hour)

3600 * 6 = 21600 (seconds in 6 hours)

3600 * 0.4 = 1440 (seconds in 0.4 hour)

21600 + 1440 = 23040 (6 hours + 0.4 hours)

your answer is 23040
