*Important Message for all*

The hot water you drink is good for your throat. But this corona virus is hidden behind the paranasal sinus of your nose for 3 to 4 days. The hot water we drink does not reach there. After 4 to 5 days this virus that was hidden behind the paranasal sinus reaches your lungs. Then you have trouble breathing.

That's why it is very important to take steam, which reaches the back of your paranasal sinus. You have to kill this virus in the nose with steam.

At 50°C, this virus becomes disabled i.e. paralyzed. At 60°C this virus becomes so weak that any human immunity system can fight against it. At 70°C this virus dies completely.

This is what steam does. The entire public health department knows this. But everyone wants to take advantage of this pandemic. So they don't share this information openly.

One who stays at home should take steam once a day. If you go to the market to buy vegetables, take it twice a day. Anyone who meets some people or goes to office should take steam 3 times a day.

Forward this to all your loved ones.

*Steam week*

According to doctors, Covid -19 can be killed by inhaling steam from the nose and mouth, eliminating the Coronavirus. If all the people started a steam drive campaign for a week, the pandemic will soon end. So here is a suggestion:

* Start the process for a week from 1st October to 8th October, morning and evening, for just 5 minutes each time, to inhale steam. If all adopt this practice for a week the deadly Covid-19 will be erased.

This practice has no side effects either.

So please send this message to all your relatives, friends and neighbours, so that we all can kill this corona virus together and live and walk freely in this beautiful world.

*Thank you*

You are welcome to send this to your known groups / friends.

Answer 2

The statement which describes the system of linear equations in two variables equations is (A) The solution set satisfies both equations.

Step-by-step explanation:

• We know, A linear equation is an equation where the degree is 1 i.e., highest variable power is 1. Also, The number of variables in a linear equation determine the type of equation if it is one variable, two variable or no variable. For example the equation $2x+5y-18=0$ is a linear equation in two variables.
• To solve a linear equation in two variables when a set of at least two equations is given, we can obtain the solutions by a variety of methods where the solution set (say x and y) satisfies both the equations. This is a necessary outcome or else the solutions cannot be determined.

Hence, The statement which describes the system of linear equations in two variables equations is (A) The solution set satisfies both equations.
