You can put this solution on YOUR website! x = one number
y = another number
x + y = 45 :: given
x = y + 9 :: y is 9 less than x
.
substitute x = y+9 in the first equation
.
y+9 + y = 45
2y = 36
y = 18
.
now substitute y=18 in the second equation
x + y = 45
x + 18 = 45
x = 27
.
checking...
Is the smaller number 9 less than the larger number?
Yes.

Answer:
The two numbers are 18 and 27.
.
Done
You can put this solution on YOUR website! Given that the sum of two numbers is 45
Let the first number by x
So the second number should be (45 - x)
Also it is given that first number is 9 less then the second number
so it means if we add 9 to first number then it would be equal to second number
x + 9 = 45 -x
2x = 45 - 9
2x = 36
x = 18
So first number is 18 and
second number is (45 - 18)= 27
