Question

If x = -9/11, y =5/7 verify that - (x + y) = (-x) + (-y)

Answer 1

x=-9/11 and y=5/7
-(x+y)=-x-y
=-9/11-5/7
=-63-55/77
= -118/77
(-x)+(-y)=-9/11-5/7
=-118/77
since L.H.S=R.H.S
hence proved

Answer 2

Step-by-step explanation:

x=-9/11 and z =5/7

-(x+y) =-x-y

=-9/11-5/7

=-63-55/77

=-118/77

(-x)+(-y)=-9/11-5/77

=-118/77

SINCE ,LHS=RHS
