.
Let x = second number
then from "One number is four more than a second number"
x+4 = first number
.
From "Two times the first number is 12 more than four times the second number" we get our equation:
2(x+4) = 12 + 4x
2x+8 = 12 + 4x
8 = 12 + 2x
-4 = 2x
-2 = x (second number)
.
First number:
x+4 = -2+4 = 2 (first number)
