Direct variation problems use the equation y = kx
Replace y and X with the two known numbers to solve for k:
6=k9
Solve for K by dividing both sides by 9:
k = 6/9, reduces to 2/3
Now replace y and k into the formula to solve for x:
15 = 2/3x
Solve for X by dividing both sides by 2/3:
X = 15 / 2/3
X = 45/2 as an improper fraction, 22 1/2 as a proper fraction or 22.5 as a decimal.
Not sure which format the answer needs to be in, so I gave all three.
45 divided by 8 is 5 r. 5. You can write this like 5 5/8 too.

Answer:
If you are doing x - 8 = 3, then x = 11
Step-by-step explanation:
Remember PEMDAS and whatever you do to one side of the equation, you have to do to the other side.
x - 8 = 3
First, add 8 to the -8 to cancel it out and isolate the variable. Since you are adding 8 to the left side of the equation, you have to add 8 to the right side as well
x - 8 + 8 = 3 + 8
Simplify.
x = 11
You can check your answer by substituting the variable.
11 - 8 = 3
This equation is true. Therefore x = 11.
