No The equation -8+(-11)/-12=(-11)/(-12)+(-8) do not equal each other. No matter how you look at it, the will never equal each other here’s some work if you need it :)
-8+(-11) = -19
Then the equation would look like this :)
-19 / -12 = (-11)/(-12)+(-8)
Now the other side :)
-12 +(-8)= -20
Leaving the equation looking as so
-19 / -12 = -11 / -20
They don’t look the same, you wouldn’t even need to solve that to know that they are not equivalent :) but if you did it would look like this :)
1.583(in repeating) = 0.55
Even so they are still not equivalent :)
Hope this helped you!! :)) have a nice day!
