A number if that number and the number b sum to 40

The problem states that two numbers, x and b , sum to 40, expressed as x + b = 40 . You can solve for either variable by rearranging the equation, obtaining x = 40 − b or b = 40 − x . This understanding is essential for mastering basic algebra.

Let's address the mathematical problem presented.
We have two numbers: one number, which we'll call x , and another number b . The problem states that the sum of these two numbers is 40.
Mathematically, this is expressed as: x + b = 40
This equation means that whatever the value of x and b are, when added together, their total is 40.
If you are asked to find one of these numbers given a fixed value for the other number, you can simply rearrange this equation to solve for the unknown number. For example, if you know the value of b , you can find x by subtracting b from 40: x = 40 − b
Similarly, if x is known and b is unknown, then: b = 40 − x
This understanding of the equation can be used to solve any problems involving numbers that sum to a given total, not just 40. It emphasizes basic algebraic manipulation, which is a fundamental skill in mathematics.
