Certainly! Let's break down the problem step by step:
1. Understanding the Problem:
The problem states that the sum of negative ten and a number is twenty. We need to determine what that unknown number is.
2. Setting Up the Equation:
Let's denote the unknown number as [tex]\( x \)[/tex]. According to the problem, the equation can be written as:
[tex]\[
-10 + x = 20
\][/tex]
3. Solving for [tex]\( x \)[/tex]:
To find the value of [tex]\( x \)[/tex], we need to isolate [tex]\( x \)[/tex] on one side of the equation. We can do this by adding 10 to both sides of the equation:
[tex]\[
-10 + x + 10 = 20 + 10
\][/tex]
4. Simplifying the Equation:
Simplify both sides:
[tex]\[
x = 30
\][/tex]
5. Conclusion:
The unknown number, when added to negative ten, that gives the sum of twenty is [tex]\( 30 \)[/tex].
So, the number you are looking for is [tex]\( 30 \)[/tex].
