Your problem seems to have an internal contradiction. See below.
Translate English into math: x is the larger and y is the smaller
x = 2y - 4
x+8 =4(y+3)
Substitute
2y-4 + 8 = 4(y+3)
2y +4 = 4y + 12
2y = -8
y=-4
x=-12
Check:
-12 + 8 = 4(-4+3)
-4=-4
But x is SMALLER!!!!
Please let me know if this solution is incorrect or not helpful.
