yes it can be possible to do
Here, take all the variables together & all the constants together as follows:
8-4m-9+m
(8-9)+(-4m+m)
-1-3m
So, your final answer is -3m-1
Hope this helps!
Answer:
In geometry, point, line, and plane are considered undefined terms because they are only explained using examples and descriptions. that lie on the same line. that lie in the same plane.
Equivalent because they are the same
You can just subtract them seperatly like this:
20-12=8
2/5-3/5= -1/5
Since its negative, you have to take 1 off of the final answer and put 4/5 so the answer is 7 4/5
Another way is making it a decimal
12 3/5= 12.6
20 2/5= 20.4
20.4-12.6= 7.8
7.8=7 4/5
