Let the number be x
hence the second number is=x+8 and
thus, 2x+12=6(x+8)
=> 2x+12=6x+48... simplifying
=>6x-2x + 48=12... subtracting 2x from both sides
=>4x=12-48 ... subtracting 48 from both sides
=>4x=-36.... simplifying
=>x=-9 ... dividing both sides by 4
Therefore the number are -9 and -1.
check:
2(-9)=-18
-18+12=-6=6(-1)
