Solve for x: x-1/2=4

Hello! I would love to help!

Let's first define solve. Solve means to get the variable, or unknown, by itself. So, we know that we've solved the equation if we get our variable, x, by itself.

Let's look at the problem like this: What number, minus 1/2, is equal to 4?

To solve this problem, let's reverse the order.

X-1/2=4

Since it is -1/2, let's add 1/2 to each side to cancel the one half out, since -1/2+1/2=0


X-1/2+1/2=4+1/2

Now, we can simplify!

X=4 1/2

That is your answer! X=4 1/2 or as an improper fraction 9/2.

I think it is a because it says the temperature is less than -5 degrees Fahrenheit
so you know the sign will have to be t<-5 degrees Fahrenheit now you are left with is t a positive or negative number a positive number would automatically be greater than -5 degrees Fahrenheit so there is no way it can be a positive number thus leaving you with one option.
