find x+y for the given system of linear equations in x and y : 1/x+1/y =2 ,1/x-1/y = 1 *0/2

Answer» 1/x + 1/y = 2 (equation-1)1/x - 1/y = 1 × 0/2 = 1/x - 1/y = 1*0 = 01/x - 1/y = 0 (equation-2)Adding equation-1 with equation-2, we get1/x + 1/x + 1/y - 1/y = 2 + 02/x = 2By cross-multiplication, we getX = 1Substituting the value of x in equation-1, we get1 + 1/y = 21/y = 1Y = 1The value of x+y is 2.
