Start at the end and work backwards:
-- The quotient of a number 'y' and 2 . . . . . ( y/2 )
-- 5 less than that . . . . . ( y/2 - 5 )
So first, write out the multiples of 15 that are less than 100
15
30
45
60
75
90
Now add up the digits and see which ones add up to 12
7+5 =12 so the answer is 75
Answer:
x = 1/14
Step-by-step explanation:
We are given the equation:
![\displaystyle \large{ \frac{2x - 1}{3} = - 4x}](https://tex.z-dn.net/?f=%20%5Cdisplaystyle%20%5Clarge%7B%20%5Cfrac%7B2x%20-%201%7D%7B3%7D%20%20%3D%20%20-%204x%7D)
Multiply the whole equation by 3 to get rid of the denominator.
![\displaystyle \large{ \frac{2x - 1}{3}(3) = - 4x(3)} \\ \displaystyle \large{ 2x - 1 = - 12x}](https://tex.z-dn.net/?f=%20%5Cdisplaystyle%20%5Clarge%7B%20%5Cfrac%7B2x%20-%201%7D%7B3%7D%283%29%20%20%3D%20%20-%204x%283%29%7D%20%5C%5C%20%20%5Cdisplaystyle%20%5Clarge%7B%202x%20-%201%20%20%3D%20%20-%2012x%7D)
Add both sides by 12x.
![\displaystyle \large{ 2x - 1 + 12x = - 12x + 12x} \\ \displaystyle \large{ 2x - 1 + 12x = 0}](https://tex.z-dn.net/?f=%20%20%5Cdisplaystyle%20%5Clarge%7B%202x%20-%201%20%2B%20%20%2012x%20%20%3D%20%20-%2012x%20%2B%2012x%7D%20%5C%5C%20%20%20%5Cdisplaystyle%20%5Clarge%7B%202x%20-%201%20%2B%20%20%2012x%20%20%3D%20%200%7D)
Combine like terms.
![\displaystyle \large{ 14x - 1 = 0}](https://tex.z-dn.net/?f=%20%20%20%5Cdisplaystyle%20%5Clarge%7B%2014x%20-%201%20%3D%20%200%7D)
Add both sides by 1.
![\displaystyle \large{ 14x - 1 + 1= 0 + 1} \\ \displaystyle \large{ 14x = 1}](https://tex.z-dn.net/?f=%20%20%20%5Cdisplaystyle%20%5Clarge%7B%2014x%20-%201%20%20%2B%201%3D%20%200%20%2B%201%7D%20%5C%5C%20%20%20%20%5Cdisplaystyle%20%5Clarge%7B%2014x%20%3D%20%201%7D)
Divide both sides by 14 to isolate x.
![\displaystyle \large{ \frac{14x}{14} = \frac{1}{14} } \\ \displaystyle \large{ x= \frac{1}{14} }](https://tex.z-dn.net/?f=%20%20%20%5Cdisplaystyle%20%5Clarge%7B%20%20%5Cfrac%7B14x%7D%7B14%7D%20%20%20%3D%20%20%5Cfrac%7B1%7D%7B14%7D%20%7D%20%5C%5C%20%20%20%20%5Cdisplaystyle%20%5Clarge%7B%20%20x%3D%20%20%5Cfrac%7B1%7D%7B14%7D%20%7D)
And we're done!
