Variables on Both Sides

I NEED TO GET HELP ON A PROBLEM TOWARDS THE END OF THE PROBLEM. I'M NOT SURE WHY THE NEGATIVE ENDS WITH A POSITIVE ANSWER IN THIS EQUATION: 4P+40=26P

You would use the following steps to solve this equation.

Step 1: Get the variables on one side of the equation by subtracting 4p from both sides.


4p + 40 = 26p
4p-4p+40 = 26p - 4p

40 = 22p

Step 2: Divide by 22 on both sides in order to isolate the variable.

40/22 = 22p/22

p = 1.82

I hope this helps!

Can this be done as a pure subtraction problem

15 - 0.75x = 13 - 0.5x

Algebra-class Response:
This is an equation with variables on both sides. Therefore, you need to add 0.5x to both sides and subtract 15 from both sides. Then you will be able to solve!

Another Variable on both sides problem:

25u+74=23u+92

Karin from Algebra Class Says:


25u+74=23u+92

Step 1: Get the variables on one side by subtracting 23u from both sides.

25u - 23u + 74 = 23u - 23u + 92

2u + 74 = 92

Step 2: Get the constants on the other side by subtracting 74 from both sides.

2u + 74 - 74 = 92 - 74

2u = 18

Step 3: Divide both sides by 2 to get the variable by itself.

2u/2 = 18/2
u = 9

The solution is u = 9.

I hope this helps,
