Let the two nos. be x and y
Now,
x + y = 70 and x - y= 16
now adding both the above statements, we get
x + y + x - y = 86
=> 2x = 86
=> x = 43
Again,
we have, x+ y = 70
=> 43 + y = 70
=> y = 70-43 = 27
hence, x = 43 and y = 27
Now,
x + y = 70 and x - y= 16
now adding both the above statements, we get
x + y + x - y = 86
=> 2x = 86
=> x = 43
Again,
we have, x+ y = 70
=> 43 + y = 70
=> y = 70-43 = 27
hence, x = 43 and y = 27
