were you able to get anywhere?

OpenStudy (anonymous):

No Sir

I Was Thinking It Was . The Work Looked Correct But I May Be Wrong.

jimthompson5910 (jim_thompson5910):

look at how the equation goes from \[\large -\frac{1}{4}x + y = 2\] to \[\large x - 4y = 2\] see the error?

@jim_thompson5910 You Have To Multiply Everything By 4 Right ?

jimthompson5910 (jim_thompson5910):

yes but notice how the right side isn't changing

jimthompson5910 (jim_thompson5910):

it's supposed to go from 2 to -8 (since you're multiplying everything by -4)

jimthompson5910 (jim_thompson5910):

so if the equation was x - 4y = -8, then it would be correct

OpenStudy (anonymous):

Oh. I Did See That So The Answer Would Be A ?

A) the work shown to isolate the constant is not correct

jimthompson5910 (jim_thompson5910):

jimthompson5910 (jim_thompson5910):

look back at what I'm saying about eliminating the fraction

OpenStudy (anonymous):

B.the work shown to remove all fractions is not correct. They did Remove The Fraction?

OpenStudy (anonymous):

Ok Ok I Understand Now. Thanks Jim!

jimthompson5910 (jim_thompson5910):

good, that's the reason why
