Question

Verify that -(x + y) = (-x) + (-y), when x = 3 upon 4 y= 6 upon 7​

Answer 1

Answer:

Step-by-step explanation:

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

-(3/4 + 6/7) = (-3/4) + (- 6/7)

= (-3/4) + (- 6/7) = (-3/4) + (- 6/7)

= − 1.60714285 = − 1.60714285

hence true

Answer 2

Answer:

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

-(3/4+6/7)=(-3/4)+(-6/7)

-(7*3+4*6)=(-7*3+-4*7)

-(21+24)=(-21+(-24))

-(45)=(-21-24)

-45=--45
