Question 662451

{{{(a+b)/c=x/d }}}...here you have two fractions; in order to eliminate a fraction, cross multiply


{{{(a+b)d=cx }}}..now you can find {{{x}}}


{{{highlight(x=(a+b)dc) }}}


or, find {{{c}}}


{{{highlight(c=(a+b)dx) }}}



or, find {{{d}}}

{{{highlight(d=c/(a+b)x) }}}


or find {{{a}}}

{{{(a+b)dc=x }}}

{{{a+b=x/dc }}}

{{{highlight(a=x/dc-b )}}}


or find {{{b}}}

{{{highlight(b=x/dc-a) }}}
