Question 1182948

please help me solve

given that log 10 2x- log 10 (x-4)=1 
 find the value of x
<pre>{{{matrix(3,3, log ((2x)) - log ((x - 4)), "=", 1, log ((2x/(x - 4))), "=", 1, 2x/(x - 4), "=", 10^1)}}} 
                2x = 10(x - 4) ------- Cross-multiplying
                2x = 10x - 40
             - 10x = - 40
              - 8x = - 40
               {{{highlight_green(matrix(1,5, highlight(x), "=", (- 40)/(- 8), "=", highlight(5)))}}}</pre>
