Is 5 a solution to the equation 3(x+1)=7(x-2)-3

Proof:

Given

To prove that the solution of   is 5,

On taking off the brackets we get,

On grouping the x terms together,

On solving we get,

On dividing 20 by 4,

Hence proved that the solution for is 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
