 Hello and welcome to the session. Let us understand the following problem today. Solve the following pair of linear equations by reducing them to a pair of linear equation given to us 1 by 3x plus y plus 1 by 3x minus y is equal to 3 by 4 and 1 by 2 into 3x plus y minus 1 by 2 into 3x minus y is equal to minus 1 by 8. Now let us write the solution. The given equations can be written as 3x plus y plus 1 by 3x minus y is equal to 3 by 4 1 by 2 into 1 by 3x plus y minus 1 by 2 into 1 by 3x minus y is equal to minus 1 by 8 and 1 by 3x minus y is equal to q. So, we get p plus q is equal to 3 by 4 plus 1 by 8 equal to minus 1. Let us name these equations as 1 and 2 minus 1. Now equal to 2 which implies 3x minus y is equal to q. So, we get here 2 q which implies 1 by 3x plus equation as 5 and 6 to 4. So, the problem, bye and have a nice day.
