How do you express a number increased by x?

To express a number increased by x, you write the number plus x, like this: number + x.

When we talk about increasing a number by x, we are essentially adding x to that number. For example, if you have the number 5 and you want to increase it by 3, you would write it as 5 + 3. This means you are adding 3 to 5, which gives you 8.

In algebra, this concept is often used with variables. If you have a variable, say n, and you want to increase it by x, you would write it as n + x. This expression shows that whatever value n has, you are adding x to it. For instance, if n is 7 and x is 2, then n + x would be 7 + 2, which equals 9.

This idea is fundamental in algebra and helps in forming equations and solving problems. For example, if you know that a number increased by 4 equals 10, you can write this as n + 4 = 10. To find the original number, you would solve for n by subtracting 4 from both sides of the equation, giving you n = 6.

Understanding how to express a number increased by x is crucial for solving various mathematical problems, especially those involving equations and algebraic expressions. It allows you to manipulate and work with numbers and variables effectively.
