medal and fan if you help me with these questions.(more than one) -6k+7k 12n-8-12 n-10+9n-3
@sooobored @jabez177 @Hayhayz @Love.Bug
any attempt yet?
yeah my attempts were wrong
please show me so i have an idea where you went wrong
love's third answer was incorrect if you saw it
1.) 1k? 2.) 12r-4? 3.) 10n-7?
for #1 i got 1k #2 i got 4-4r #3 i got 10n-13
1 is right, as a note, "1k" is the same as "k" since anything times 1 is the same value
okay what about the others
3 is fine, but 2 is wrong
okay so what did i do on two that was wrong
12r-8-12 unless the question is different than as shown, your answer 2 was absolutely completely wrong
you just add up like terms or we can group them up 12n +(-8-12)
we'll notice that there is no other term with the variable n so we can leave 12n alone the only like terms we see are -8 and -12 adding those together and you get?
-20?
yea so add that together with 12n the complete answer is?
12n+20
?
you wrote -20, whered +20 come from?
oops i meant 12n-20
yup
well except, variable is r not n soooo
just make sure the proper variable is in the answer
oops i meant to put n oops
any other questions regarding above problems?
