A pair of consecutive integers has the property that 8 times the lesser is more than 4 times the greater.
Find the least pair of integers with this property.

 

 

what I did was: 

8x>4(x+1) 

x=1

 

did I do this correct??

Not QUITE correct Guest ....

 

8x > 4(x+1)

8x > 4x + 4

4x > 4

x > 1       Since it is an interger set we are looking for and 'x' must be greater than 1 ..... so 'x' = 2   and the other number is 3

If x = 1 then the left hand side is 8x1 → 8 and the right hand side is 4(1 + 1) → 8, so the left hand side is not greater than the right hand side.
