Question 89322

X + .085X = 743.75

Get rid of the decimals:

Since the maximum number of decimal places any of the
numbers has is THREE, then we multiply every term
by 1000 (1 with THREE zeros after it)

(1000)X + (1000)(.085X) = (1000)(743.75)

            1000X + 85X = 743750
    
                  1085X = 743750

                      X = {{{743750/1085}}}

                      X = 685.483871
