I really need help! I have a paper due tomorrow and I can't find out this answer. Can you help me? The question says this: -2=n+5. Under it it says: (-2)-____=n+5-____. I know that n equals -7 but I can't find out the blanks. Please help!
-2=n+5
-2 - 5 = n +5 -5
-7 = n
Thank you Ms. Sue!
You're welcome, Lizzy.
Of course, I'm here to help you! Let's work through the problem step by step.
The original equation is -2 = n + 5. To solve for n, we need to isolate it on one side of the equation. We can do this by performing the same operation to both sides of the equation.
First, let's subtract 5 from both sides to move it away from n:
-2 - 5 = n + 5 - 5
This simplifies to:
-7 = n
Now, let's move on to the second part of the question which asks you to fill in the blanks in the expression (-2) - ____ = n + 5 - ____.
We know that n equals -7, so we can substitute -7 into the equation:
(-2) - ____ = (-7) + 5 - ____
This can be simplified as:
-2 - ____ = -7 + 5 - ____
Now, we need to evaluate the expression on the right side:
-2 - ____ = -2 - ____
Since we don't know what the missing values are, we can use a placeholder, such as "x":
-2 - x = -2 - x
To solve for "x," we need to perform the same operation to both sides of the equation. In this case, we can subtract "x" from both sides:
-2 - x - (-x) = -2 - x - (-x)
This simplifies to:
-2 - x + x = -2 - x + x
The "x" terms on the left side of the equation cancel out, leaving us with:
-2 = -2
This equation is true for all values of x. Therefore, the value of the blank can be any number.
To summarize, the blanks in the expression (-2) - ____ = n + 5 - ____ can be filled with any number because the expression simplifies to -2 = -2 regardless of the value of the missing terms.
