1. Answer :

   • 7x + 6x = 180 is the Linear equation in two variables

   Given :

   • The sum of 7 times the number of boys
   • 6 times is the number of girls
   • Total is 180 in a class

   To find :

   • Linear equation in two variables

   Solution :

   • Let the number of boys be x
   • Let the number of girls be y

   • Number of boys is 7 times
   • Number of girls is 6 times
   • Total number is 180

   According to question,

   Now we have to write in Linear equation in two variables :

   》7x + 6x = 180

   Hence , 7x + 6x = 180 is the Linear equation in two variables

   More Explanation :

   • The pair of values of the variables x and y which together satisfy each one of the equation is called the Solution for a pair of linear equation
   • A pair of linear equation in two variables can be solved using various methods
   • A graph of linear equation in two variables is represented by two lines

   7x+6y=180

   Step-by-step explanation:

   let the number of boys be x

   let the number of girls be y

   then,

   7x+6y=180
