 Hi and welcome to the session. I am Deepika here. Let's discuss the question solve the following equation 10p plus 10 is equal to 100 So let's start the solution our given equation is 10p plus 10 is equal to 100. Now We want to separate the variable p. So First let's subtract 10 from both sides subtract from both the sides of the above equation we get 10p plus 10 minus 10 is equal to 100 minus 10 or 10p is equal to 90 Now divide both sides of the above equation above equation by 10 Why doing so? We will get p on the left hand side So we get 10p upon 10 is equal to 90 upon 10 or P is equal to 9 and this is a required solution Hence the answer for the above question is P is equal to 9. I hope the question is clear to you. Bye and take care
