Question

-5.19(y-10)+6.1=3(y-6.6)+4.3

its asking for exact form,no decimals and simplified if possible.

then asking for decimals rounded 4 places

Answer 1

First of all, I would multiply each term by 100
519(y-10) +610 = 300(y - 6.6) + 430
519y - 5190 + 610 = 300y - 1980 + 430

look, no decimals, no fractions,
take over

Answer 2

i got 1010/73 and 13.8356 and they bith were counted wrong?

Answer 3

both

Answer 4

too bad you don't show your work. Just doing the decimal values, I get 8.97436

I agree with your evaluation of Reiny's final line, so let's see what went wrong. Did you bother to check his math?

His only mistake was to omit the leading minus sign. Had you corrected that, you would have arrived at

-519(y-10)+610 = 300(y-6.6)+430
-519y+5190+610 = 300y-1980+430

y = 350/39

If you get a wrong answer here, don't just fold your arms and sulk. See if a simple typo was made.
