 Hello and welcome to this session. Let us understand the following problem today. Solve the following pair of linear equations by reducing them to a pair of linear equations given to us 7x-2y by xy is equal to 5 and 8x-7y by xy is equal to 15. Now let us write the solution. The given equation can be written as 1x-2y is equal to 5xy and 8x-7y is equal to 15xy. Now dividing both sides equation 1 and equation 2 can be written as we get equations 5, equation 5, equation 6, 35, 49, 14, x is equal to q. On solving this we get this implies 1 by y is equal to 1 implies 1 by x is equal to 1 equal to 1 and this implies x is equal to 1. But it should be problem by an a...
