ivanzaharov [21]

Step-by-step explanation:

s =  \frac{a}{a - r}

multiply both sides by a - r

(a - r)s = a

divide both sides by s

a - r =  \frac{a}{s}

subtract a from both sides

- r =  \frac{a}{s}  - a

invert the signs

r =  -  \frac{a}{s}  + a

The sum of two numbers is 24. The first number is 3 less than 8 times the second. Find the two numbers. Please show your work
Dmitry_Shevchenko [17]

9514 1404 393

Answer:

  21, 3

Step-by-step explanation:

Let the first and second numbers be x and y, respectively. Then we have ...

  x + y = 24 . . . . their sum is 24

  x = 8y -3 . . . . . the first is 3 less than 8 times the second.

Substituting for x in the first equation, we have ...

  (8y -3) +y = 24

  9y = 27 . . . . . . . . add 3

  y = 3 . . . . . . . . . . divide by 9

  x = 8(3) -3 = 21

The two numbers are 21 and 3.
