Solve for w. 20.5=w/60^2*703 can someone explain this to me? i don't know what to tysm.

It looks like you have

Then the coefficient of w is 703/3600. Multiply the equation by the reciprocal of that and you will have your answer.

_____

If the variable of interest is found in one term of the equation, and there are no other terms on that side of the equation, you can find the value of the variable by multiplying the equation by the inverse (reciprocal) of the variable's coefficient.

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
