7. Two numbers are such that is 9 is added to the first number, so the number become three times the second number. And ,if 22 is added to the second number So the number obtained is twice the first number. Find the differences both of number!
[tex]a =the \: first \: number \\ b =the \: second \: number \\ \\ 9 + a = 3b \\ a = 3b - 9 \\ \\ 22 + b = 2a \\ 22 + b = 2(3b - 9) \\ 22 + b = 6b - 18 \\ 22 + 18 = 6b - b \\ 40 = 5b \\ \frac{40}{5} = b \\ b = 8 \\ \\ a = 3b - 9 = 3(8) - 9 \\ a = 24 - 9 = 15[/tex]
The difference both of number
15 - 8 = 7

15. A number when divided by 4 and subtracted from 12 gives the same result as when 1/6 is multiplied to the number. Find the number.
Misalkan ankanya X, maka...
[tex] \frac{x}{4} [/tex] + 12 = [tex] \frac{1}{6} [/tex] × X
[tex] \frac{x+48}{4} [/tex] = [tex] \frac{x}{6} [/tex]
3X + 144 = 2X
3X - 2X = -144
X = -144
