Best ResponseYou've already chosen the best response.1you made an error in line 2... you multiplied 4 by 6 in line 1 and replaced it with 24 in line 2... should have been +24

Best ResponseYou've already chosen the best response.04t + 24 + t + 6 = 7 4t + t+ 24 + 6 = 7 3t + 30 = 7 3t  30 + 30 = 7  30 3t = 23 Divide t = 7.8 Now switch t = 11/5

Best ResponseYou've already chosen the best response.1Except that last step isn't right, I don't think... 3t = 23 divide both sides by 3 3t/(3) = 23/(3) t = 23/3 That doesn't reduce any further... you can get it as a decimal if you want... 7.666667, but 23/3 is correct too.

Best ResponseYou've already chosen the best response.0You can reduce 7.6 a little further to make it clear. But that's a different form of mathematics. I'd just go with 7.6

Best ResponseYou've already chosen the best response.1I'm not sure I follow... 23/3 is equal to 7 and 2/3 as a mixed fraction, or you can write the 2/3 as a decimal, rounding off wherever you feel like. But you wouldn't want to round to 7.6. Anyway, the algebra is the more important part... @vortish, the steps you followed were good, and if you had not made that mistake early on, you probably would have been fine through the rest.
