By substitution method 1. x+y=14, x-y=4

1.	By substitution method 1. x+y=14, x-y=4
Answer» x+y=14----------------- (1)x-y=4----------------(2)From 2 x=4+y Substituting value of x in equation 14+y+y=144+2y=142y=14-42y=10y=10/2y=5As x+y=14 x+5=14x=14-5x= 9x=9y=4 x+y=14 ......... (i)x-y=4 .......... (ii)Adding (i) and (ii)2x = 18x = 18/2 = 9Put x = 9 in (i)9 + y = 14y = 14 - 9y = 5
