If twice the opposite of a number increased by five, then the result is the opposite of a number. What is the number?
What is this even asking off me?
The easiest way to solve this is the guess and check method. It is asking you what a number doubled then by adding five is the opposite of that number. Now go through a few SINGLE digit numbers to try and solve. I hope this helps.
Oh thank that did help :D
This question is asking you to find the number that satisfies the given condition. Let's break it down step by step to understand it better and find the solution:
Step 1: Let's assign a variable to represent the unknown number. Here, let's assume the number is "x".
Step 2: "Twice the opposite of a number" can be expressed as "-2x" because the opposite of "x" is "-x" and twice that is "-2x".
Step 3: Now, the statement says that if we increase "-2x" by five, we get the opposite of the number. Mathematically, we can represent this as "-2x + 5 = -x" because the result is the opposite of the number.
Step 4: To find the solution, we need to solve this equation for "x". Let's do that:
-2x + 5 = -x
Subtract "-x" from both sides:
-2x + x + 5 = 0
-x + 5 = 0
Subtract 5 from both sides:
-x + 5 - 5 = -5
-x = -5
Multiply by -1 to solve for "x":
(-1) * (-x) = (-1) * (-5)
x = 5
Step 5: So, the number that satisfies the given condition is "x = 5".
