You can put this solution on YOUR website! First lets give each number a variable
We will call one number x
and the other number we will call y
Given: the sum of two numbers is 40 so
Given: their difference is 8 so
Now take the first equation and set it equal to x
To do this subtract y from both sides of the equal sign
Now take the second equation and replace the x with 40-y
So now that we have found y equals 16 we can replace the y in either of our original equations and solve for x
Now we have found the two numbers
x=24 and y =16
Check these by trying them in both of the original equations so
and the other
They both work so we know we have correctly found the numbers.
