OpenStudy (anonymous):

its 10x-5 over 5

OpenStudy (phi):

think of when you add fractions with a common denominator 1/4 + 2/4 = (1+2)/4 here, do the opposite change (1+2)/4 back to 1/4 + 2/4

OpenStudy (anonymous):

1 over x?

OpenStudy (anonymous):

is that the answer

OpenStudy (phi):

is the problem \[ \frac{10x-5}{5} \]

OpenStudy (phi):

?

OpenStudy (anonymous):

yea

OpenStudy (anonymous):

nooo

OpenStudy (phi):

can you break it up into 2 fractions?

OpenStudy (anonymous):

OpenStudy (anonymous):

ten over x subtract 5 divided by 5

OpenStudy (phi):

you mean \[ \frac{\frac{10}{x} -5}{5} \]?

OpenStudy (anonymous):

yea

OpenStudy (phi):

if you multiply the top and bottom by 1/5 what do you get?

OpenStudy (phi):

do the bottom first: (1/5)*5=?

OpenStudy (anonymous):

5 over 5 equals 1

OpenStudy (anonymous):

i really need the answer asap

OpenStudy (phi):

now do the top: \[ \frac{1}{5}(\frac{10}{x}-5) \]

OpenStudy (anonymous):

i dont have time

OpenStudy (phi):

you multiply 1/5 times each term in the parentheses
