ALGEBRA EXTREMELY NEED HELP
posted by Katie .
HOW DO YOU SOLVE (2c/c-4)-2=(4/c+5). WHAT IS THE LCD. HOW DO YOU FIND IT BECAUSE I NEED TO KNOW
ummm... i feel srry 4 u...tht looks REALLY hard...
search for algebra slover on here...it should no the answer...
It is and believe it or not I am crying because I have a test tomorrow
I suspect you mean
[ 2 c/ (c-4) ] - 2 = 4/(c+5)
LCD if I have your question right is (c-4)(c+5)
which by the way is c^2 + c -20
som ultiply all terms by (c-4)(c+5)
2 c (c+5) -2 (c^2 + c - 20) = 4 (c-4)
2 c^2 + 10 - 2 c^2 -2c + 40 = 4 c - 16
66 = 6 c
c = 11
I don't think that is the correct answer, according to my book it says the answer is -14. I got the same LCD you did
NEVERMIND your somewhat right,yet wrong answer helped me and I got the right answer.
