Answer these 4 questions for brainliest! :) For questions 1 - 4, simplify the variable expression as much as possible.

1. x + 4 - 3 + 1
2. x - 5 + 5x + 2
3. 2x + 7 - 4x - 8
4. (4 + 3)x + 2x - 5

thank you for your help and have a blessed day!

1. X+2

2. 6x-3

3. -2x-1

4. 9x5

Step-by-step explanation:

1. X+4-3+1 There is only one variable, so you don’t need to worry about that. Just do all of the numerical operations. 4-3+1= 2. So it would be x+2

2. X-5+5x+2. Again, do the numerical operations first. -5+2=-3. X+5x=6x. So it would be 6x-3.

3. 2x+7-4x-8. 7-8=-1. 2x-4x=-2x. So it would be -2x-1.

4. (4+3)x+2x-5. Do the operation in the parenthesis first. Then it would be (7)x or just 7x+2x-5. Simplify to 9x-5.

water molecules will move from the side of higher water concentration to the side of lower concentration until both solutions are isotonic. at this point, equilibrium is reached. in an isotonic solution, the flow of water in and out of the cell is happening at the same rate.

hope this < 3
