yes

Answer 4

so are the +6 and -3

Answer 5

Now when you combine do you leave the numbers that cannot be combinded at the END of the equation? @jim_thompson5910

Answer 6

or you can place them wherever you want, just don't combine them with other terms

Answer 7

for instance, -x and 6 are NOT like terms so you don't combine them to get -5x or -5

you just leave it as -x+6
