Question

The product of two numbers is 70 to the larger number is four more than three times the smaller number find them

Answer 1

Answer:The larger number is y = 70 - x = 70 - 22 = 48

Step-by-step explanation:Let x and y be the two unknown numbers.

The sum of two numbers is 70:  x + y = 70

The larger number (y) is 4 more than twice the smaller number (x):  y = 2x + 4

 

Since x + y = 70, y = 70 -x.  Substitute 70-x in place of y in the second equation:

 

     y = 2x + 4

     70 - x = 2x + 4

     70 = 3x + 4

     66  = 3x

     

    22 = x  (This is the smaller number)

 

The larger number is y = 70 - x = 70 - 22 = 48
