I Need Help Im Really Confused With This If Your Explanation Is Good Then Ill Give Brainiest And 5 Stars class=

Sagot :

Answer:  12x - 8y

Explanation:

Focus on the x terms for now. We have 10x and 2x. Saying 10x+2x is like saying "10 boxes +  2 boxes = 12 boxes". We can replace "boxes" with "x" to say 10x+2x = 12x

The y terms are a similar story, and -5y-3y = -8y. It might help to set up a number line to see why -5-3 turns into -8.

Answer:

12x - 8y

Step-by-step explanation:

=> 10x - 5y + 2x - 3y

=> (10x + 2x) + (-5y - 3y)

=> 12x + (-8y)

=> 12x - 8y
