m=25
21 is the only solution of that equation.
m3 + m4 ≠90
The solution is k = 9.
Y=-6
56???
7 and (-3/2)
If you mean 28 = 7+y then the solution of the equation is y = 21
x = 3, y = 3
The solution (not sum) to the equation 21 = 3c + 6 is as follows:21 = 3c + 621 - 6 = 3c + 6 - 615 = 3c3c = 153c/3 = 21/3c = 7
2x - y = 15 2x + 3y = -21 As you observe both equations (having different slopes), you see that the system is consistent, and it has only one solution.
When the dissolving rate equals the rate at which molecules comes out of solution the solution is in 'equilibrium'.
A solvent plus a solute equals a solution.
