Answer:
2
Step-by-step explanation:
-x = 4 -3x + 6
First, let's get x on one side.
Add 3x to both sides.
-x + 3x = 2x
-3x + 3x = 0
We now have:
2x = 4 + 6
Combine like-terms (add 4 to 6)
4 + 6 + 10
2x = 10
Divide both sides by 2 to solve for x.
2x / 2 = x
10 / 2 = 5
We're now left with:
x = 5
I hope this helps!
Answer:
185.714% increase
Step-by-step explanation:
To find the percentage increase, take the new amount and subtract the original amount
40-14 = 26
Divide by the original amount
26/14
1.857142857
Multiply by 100% to change to percent form
185.714%
Answer: x= -5
Step-by-step explanation:
- Combine like terms: 7/2x and 1/2x are like terms--> adding them we get 8/2x or 4x
- Isolate x by subtracting 9/2x from the other side, getting us -1/2x= 2 1/2
- Multiply by -2 to get x= -5
These steps are the same for solving all equations with one variable.
