Question 8614
Are you solving for x??  If so, you must get the x terms all on one side, which you have already, and then get the x in one place, by FACTORING out the x.

tx -ux = 3t
x(t-u) = 3t


Now, divide both sides by the factor that is multiplied times x, which is (t-u).

{{{ (x(t-u))/(t-u) = (3t)/(t-u) }}}

{{{x= (3t)/(t-u) }}}
