a number is twice another number when the larger is subtracted from 50 the result is it 2 more then when the smaller is subtracted from 40 find the number

Answer 1

the number is 40-24=16

Answer 2

Let the smaller number be x. And the lager number be 2x . There fore from the above condition we get the equation ad follows:

(50-2x) +2 = 40-x

or, 52-2x = 40-x

or, 52-40 = 2x-x

or, 12=x

Therefore the required number is 12
