Question

Solve the following systems of equations:
1/(3x+y)+1/(3x−y)=3/4
1/2(3x+y)−1/2(3x−y)= −1/8

Answer 1

Then the given equations

Equations (3) and (4) from a pair of linear equations in the general form. Now, you can use

any method to solve these equations. 

Hence,x= 4, y =5  is the required solution of the given pair of equations.
