Question 25162
Let x = time it will take them together to do the job.

1/8 = amount of the job the experienced accountant can do in 1 hour.
1/23 = amount of the job the novice can do in 1 hour.
1/x = amount of the job they can do together.


{{{1/8 +1/23= 1/x}}}


Multiply both sides by the LCD which is {{{23*8*x}}}

{{{1/8 +1/23= 1/x}}}
{{{23*8*x *(1/8) + 23*8*x*(1/23) = 23*8*x*(1/x)}}}

{{{23x + 8x = 23*8}}}
{{{31x = 184}}}
{{{x = 184/31= 5.935}}} approximately!
