What is the actual question? I know what you're trying to say, just it's not enough info...
3+2 = 5
30 / 5 = 6
so
3 x 6 = 18
2 x 6 = 12
answer
ratio 3: 2 =18:12
Y = 3x + 15
y = 2x + 8
3x + 15 = 2x + 8
-2x -2x
——————-
x + 15 = 8
-15 -15
—————-
x = -7
Hey there!
The key word in there is Many more. Whenever you see that word, it usually means to subtract
So you would subtract 4.5 from 8.1
8.1
-4.5= 3.6
