Question

Can someone one please explain this to me and what to do it say combing like trems ​

Answer 1

you just combine the terms with the same variables
so
2x+3-2y+3x+3y
you would add the like terms

by the way, each one keeps the sign before it and if it doesent have a sign for example at the beginning, its positive
2x+3x= 5x

3 (theres only one without a variable so no need to add)

-2y+3y= 1y aka y
sooo
your answer is 5x+3+y
or 5x+y+3 cuz the order doesnt matter for addition

Answer 2

A. 5x+y+3

Explanation:

to combine like terms you get the numbers that have the same variable. you will combine 2x and 3x and to combine them you add them 2x+3x and it equals 5x. you will do the same for the numbers left... -2y and 3y = 1y or y and 3 is left so we dont do nothing and after you do that you will put it in an equation variables go first and you order them in alphabetical order so 5x will go first then y and lastly the 3
