18-6x=96

Nnesha (nnesha):

18 is positive on left side what is opposite of positive ???

OpenStudy (anonymous):

when 18 is subtracted from 6 times a certain number , the result is 96

Nnesha (nnesha):

so you have to translate that ????

OpenStudy (haichi):

96-18 is wat?

OpenStudy (haichi):

Answer divided by 6

OpenStudy (ahsome):

Equation: \[18-6x=96\] Move the 18 to the RHS\[-6x=96-18\]\[-6x=78\]Divide both sides by \(-6\) \[\frac{-6x}{-6}=\frac{78}{-6}\]\[\frac{\cancel{-6}x}{\cancel{-6}}=\frac{78}{-6}\]\[x=\frac{78}{-6}\]\[x=-13\]

OpenStudy (mathmale):

Please be certain to include the instructions that came with this problem. The problem should read as follows: "Solve 18-6x=96 for x."

Nnesha (nnesha):

when 18 is subtracted from 6 times a certain number , the result is 96 is this your question ????

OpenStudy (ahsome):

@Nnesha, yes

OpenStudy (anonymous):

yes I had to answer it and the solve it and once I solved I had to check it. my answer came to -13 like what ajsome said but when I checked it. it came out wrong ?

Nnesha (nnesha):

ok thanks for explaining i thought you just have to translate that

OpenStudy (ahsome):

Then maybe the questions you are asking is wrong?

Nnesha (nnesha):

|dw:1417668194413:dw| nope this right

Nnesha (nnesha):

-6 time - 13 then add 18

OpenStudy (mathmale):

Ahsome has found a tentative solution. Please check that solution by substituting x=-13 into the original equation. Is the resulting equation true or false? Implications?

OpenStudy (anonymous):

nnesha I just didn't add. that confused me but thank you very much

OpenStudy (mathmale):

What is 18-6(-13)?

OpenStudy (mathmale):

(see original equation)

Nnesha (nnesha):

\(\color{green}{my :) pleasure :)}\) be careful next time

OpenStudy (anonymous):

I will /.^ thanks for being so patient @Nnesha

Nnesha (nnesha):

:)
