find two positive numbers if one is three times the other and their difference is 8. This question is from textbook

one positive number=x-----------------because you need to assign a variable to solve for
other positive number=3x-----------------because it is three times the other
difference=8

Therefore,
3x-x=8----------------------------------because their difference is 8

Combine like terms (the x's)
2x=8

Divide both sides by 2
x=4

one positive number=x
other positive number=3x

Plug in x
First number=(4)
Second number=3(4)

So,
First number=4
Second number=12
