-5=-1-4
-5=-5

-1- =-5
-1 minus what will be -5

-5=-5

1-(-4)=1+4

Studentka2010 [4]

Statement 3 is QR=RT. This can be validified by the reason of Transitive Property of Equality. This property is applied when the situation is if a=c and b=c, then a=b. The same is true for QR=59 and RT=59, then QR=RT.
