We can write this in math as x+y+z=104, x=y-6, and z=3y
Because we already know what x and z are in terms of y, we can substitute our values for x and z into the first equation. This now looks like (y-6) + y + (3y) = 104. Now we can simplify our equation to find our value for y.
y-6 + y + 3y = 104 simplifies to 5y - 6 = 104, then 5y=110, and finally y=22.
Now that we know our value for y we can find our values for x and z by substituting our value for y into the other two equations.
The second equation x = y-6 can be simplified as x = 22 - 6 and further simplified as x = 16.
The third equation z = 3y can be written as z = 3(22) or z = 66.
Our three numbers are 16, 22, and 66. Hope this helps you!
Answer: X can not be 11 or higher, so that means this problem will be 10 or lower. There for the value of X=6

$128.49
Step-by-step explanation:
4 gallons at $15.72 each is 4×$15.72 = $62.88
3 gallons at $21.87 each is 3×$21.87 = $65.61
The total purchase is ...
$62.88 +65.61 = $128.49
