Best ResponseYou've already chosen the best response.2when you take out 9 from 18x what will u have left ?

Best ResponseYou've already chosen the best response.2yes right so combine them 6x+1x=?

Nnesha

Best ResponseYou've already chosen the best response.2yes right so 3(6x+2+x) is 3(7x+2)

Best ResponseYou've already chosen the best response.07x+2= 9 3x9=27 18x+9=27 they both equal 27

Best ResponseYou've already chosen the best response.2first of how did you get 9 how 7x+2 equal to 9 ?

Nnesha

Best ResponseYou've already chosen the best response.22nd i just told you can't combine a number with variable with number without variable like 18x+9=27 18 have x variable but 9 doesn't so they are not like terms

Best ResponseYou've already chosen the best response.2\[\huge\rm 3(6x+2+x)=3(7x+2)\] so which answer choices is same as 3(7x+2) ?

Best ResponseYou've already chosen the best response.2do you mean combine 21x and 6 ?

anonymous

Best ResponseYou've already chosen the best response.0no i mean 3(7x+2) and 21x + 6 they both have a variable so you can combine them

Best ResponseYou've already chosen the best response.2you need two expression that are equivalent to 3(6x+2+x) (same as 3(7x+2) now you can see one of answer choice is 3(7x+2) so 3(7x+2) is equivalent to 3(7x+2)

Best ResponseYou've already chosen the best response.2here are some example of like terms 4x+3x=7x 4y+4y= 8y 4x+3 isn't equal to 7x no! you can't combine 4x with 3 they are not like terms

Nnesha

Best ResponseYou've already chosen the best response.23 times 2 = 6 right ? dw:1438799303607:dw so 3(7x+2) is equivalent to 21x+6

anonymous

Best ResponseYou've already chosen the best response.0so 27x is the answer

Nnesha

Best ResponseYou've already chosen the best response.221x+6 is just 21x+6 you CAN'T combine them they are NOT LIKE terms

Best ResponseYou've already chosen the best response.0i see im not suppose to do anything after that i was doing 21x+6=27x i thought i had to finish the problem...

Best ResponseYou've already chosen the best response.2no you can't combine 21x+6 its just like making milkshake of mangoes and onion
