Question

Please Answer this my friend needs a help, Twice the smaller number of nine less than the larger number if the difference of the two numbers is 15 find the numbers.

Answer 1

let smaller number = x and larger = y then
do u mean 'smaller number IS nine less than larger number'?

Answer 2

X-Y=15
and
x-2y=9
hence
y=6 (I - II)
and
x=21

Answer 3

that is if twice the smaller number is 9 less than the larger number

Answer 4

i assume u do so
2x = y - 9
y - x = 15

adding eliminates y:
x = 6
and plug x=6 into
second equation
y - 6 = 15
y = 21

answer
(6,21)
