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
To solve the equation 4 - x = -5, you need to isolate the variable x. Here are the steps:
1. Start with the equation 4 - x = -5.
2. To isolate x, you want to get rid of the 4 on the left side of the equation. You can do this by subtracting 4 from both sides of the equation.
4 - x - 4 = -5 - 4
-x = -9
3. Now, to solve for x, you need to get x alone on one side of the equation. Since -x means -1 * x, you want to divide both sides of the equation by -1 to cancel out the -1 coefficient in front of the x.
-x / -1 = -9 / -1
x = 9
So, the correct solution to the equation 4 - x = -5 is x = 9.
To check your answer, you can substitute x = 9 back into the original equation and see if it holds true.
When x = 9,
4 - x = 4 - 9 = -5, which matches the right side of the equation.
So, the answer is indeed x = 9 and not -9.
