Question 253780
let x = the number


{{{6/(x-1) = 15/2x}}}


multiply both sides of equation by {{{(x-1)*(2x)}}}


result is:


{{{6*2x = 15*(x-1)}}}


simplify to get:


{{{12*x = 15*x - 15}}}


subtract 12*x from both sides of the equation and add 15 to both sides of the equation to get:


{{{3*x = 15}}}


divide both sides of the equation by 3 to get 5
