To find an expression for the other number, let's assume the first number is x. Given that the sum of the two numbers is 15, we can set up the equation:
x + y = 15
Here, y represents the other number we're trying to find. To isolate y, we can subtract x from both sides of the equation:
y = 15 - x
So, the expression for the other number is 15 - x.
