"For the past x laps around the track, Steven's average time per lap was 51 seconds. If a lap of 39 seconds would reduce his average time per lap to 49 seconds, what is the value of x?" A) 2 B) 5 C) 6 D) 10 E) 12
I would appreciate if you can solve this without using Plug in numbers so that I 'll see the concepts better. Tks!.

see, for x laps, steven's avg. time per lap was 51 sec...that means he has run for a total of 51x seconds till now..when he completes another lap of 39 seconds, total time steven has run = 51x + 39 and total laps steven has run = x+1
now, his avg. time per lap = (51x+39)/(x+1) which is given to be equal to 49 seconds

A lap of 39 seconds takes out (51-39)12 seconds...whereas the actual reduction in average is 2 (51 to 49)...so there should be 6 laps including the last one of 39...
Ok (I have trouble pasting my ecuations here) X is different from - 1/2 Then 6x2+11x - 7 2x-1 = (X is different from minus one half; then six (X elevated to the 2 power), plus 11X, minus 7 all this divided by 2x minus 1, equals...)

If x is 1/2 , then 6x2+11x 7 / 2x-1= I would appreciate some algebra solving, tks!
hi..first of all, i think the condition is x is not equal to +1/2....cuz if thts the case, then the equation becomes equal to infinity since the denominator equals zero....so considering tht case,
6x2+11x-7 can be written as (3x+7)(2x-1)...(2x-1) cancels with the denominator...so we are left with (3x+7).
