Which Which of the following is not a solution?
( Solids, liquids, or gases). Two different states when mixed are not considered as a solution. Example: Soil contains solids and liquids hence it is not a solution. Seawater is considered a solution because the salt in seawater is completely dissolved and is a homogeneous mixture.

Salt water is a solution because it has these two characteristics: it has the same concentration of each of its parts throughout the solution, and it can be separated by some physical process. stands for the element hydrogen, and the O stands for the element oxygen.
Air is not a colloidal solution because it is a homogeneous mixture of different gases.
The Correct Answer is Option 1 i.e Milk.
Every time you cheat, you're not learning skills and lessons that could be important later on. Cheating is disrespectful. Teachers work hard to share knowledge to help you be successful in academics, career, and life. Cheating shows a lack of respect for the efforts of your teacher and your classmates who did the work.

Answer: d. (2,3) is not a solution of 3 X + 4 y is equal to 12.
Answer: D) (3, 1) is not the solution .
Which of the following is not the solution of 2x 3y 6?
Answer: Option (b) (3,-4) is answer.
Hence (1,3) does not lie on 2x+y=7.
x = 6, y = -3/2 is the solution of the equation 3x + 4y - 12 = 0.
From the question, we can see that 3x-4y =12 is an equation of two variables x and y.
Any three solution for the equation 3x+4y=12.
As the value of \(x (= 5)\) and \(y (= 3)\) does not satisfies any of the given equation, hence \(\left( 5, 3 \right)\) is not a solution of the pair of equations \(3x - 2y = 4\) and \(6x- 4y = 8\).
As the value of x(=5) and y(=3) does not satisfies any of the given equation, hence (5,3) is not a solution of the pair of equations 3x−2y=4 and 6x−4y=8.
Therefore, the pair of equations has infinitely many solutions. Explanation: Because the two lines definitely have a solution.
If the result is five, then that pair of values form the solution set of the given equation otherwise, not the solution. Since the result is 5, the set of values of x and y satisfy the equation. Therefore, the last set of values is not the solution of the given equation. So, the correct answer is option 4.
(0,2) and (3,0) are the two solutions of the given equation.
What is the solution of the equation 8x 3y 5 and 3x 2y 5 *?
Answer. Answer: The solution of the given linear equations is ( x, y ) = ( 1, - 1 ).
Answer : (0,7),(1,5),(2,3) and (-1,9).
Hence, given equation has total 3 variables .
The four solutions of the equation 2x + y = 7 are (0, 7), (1, 5), (2, 3) and (-1, 9). (0, 9) is the solution.
