jdoe0001 · Answer

a number less than 21 by 3 units,  would be less than 21 by 3 units

a number more than 21 by 3 units, would be more than 21 by 3 units

so... what do you think?

texaschic101 · Answer

x = greatest number....so we know 21 is the biggest. The other number is 3 less ....that means 3 less then the greatest number....3 less then 21

anonymous · Answer

@texaschic101 So the greater number would be 18?

texaschic101 · Answer

greatest number is 21
3 less would be (21 - 3) which is 18

so your two numbers are 21 and 18
