Question

when combining like terms what do you do with a letter by itself?? example -6y + 6 - 4 + 2 + y - 4

Answer 1

what do i do with the y?

Answer 2

the coeffitient of the letter is 1

Answer 3

so y=1y

Answer 4

"combining like terms" is really just applying the UNdistributive property and factoring out a greatest common factor

Answer 5

commute all terms with a common factor and associate them into one group

-6y + 6 - 4 + 2 + y - 4

( -6y+y) + (6 - 4 + 2 - 4)

factor out the greatest common factor of "y"

y(-6+1) + (6 - 4 + 2 - 4)

and thats pretty much it
