Homework Help: Algebra

Posted by Angie on Saturday, June 27, 2009 at 2:22am.

Please Solve:

4-x=-5

I thought the answer was -9 but that doesn't seem to be it. Can someone please help? Thanks!

This is what I have:

6. 4-x=-5
The problem to solve is:
4-x=-5

Subtract 4 from both sides

x = -9 Then divie by -1

Would the answer be 9?

To Check:

4- - 9 = -5

My mistake 4-(9) = -5 ? This is what I believe to be the correct answer

you had:
4-x=-5

Subtract 4 from both sides

x = -9

that should have been

-x = -9

now divided by -1 to get
x = 9
