Question

if x is equal to -4/7 and y is equal to 2/5,then verify that: -(x+y) is equal to (-x)+(-y)​

Answer 1

Answer:

given-x=-4/7 and y= 2/5

x+y=-4/7+2/5=-1/5

-(x+y)=1/5

-x+(-y)=4/7-2/5=1/5

hence -(x+y)=-(x)+ (-y)

Answer 2

Answer:

LHS = -(x+y)

=-4/7+2/5

=-{(-20+14)/35 }

=-(-6)/35

=6/35

RHS =(-x)+(-y)

= -(-4/7)+(-2/5)

=4/7-2/5

= (20-14)/35

=6/35

So -(x+y)= (-x)+(-y )
