the greater of two numbers is 3 less than twice the smaller number. the sum of the number is 18. what are the two numbers?

Sagot :

Let smaller number = x
      greater number = 2x-3
Sol. : 
  x + 2x - 3 = 18
  3x = 18 + 3

3x  = 21   or x = 7  

Therefore smaller number : x = 7
               greater number:  2x - 3    = 2 (7) - 3  = 11
