Question 818994
Assuming only one variable, x.  The capitalization seems strange; either use x or X.  Not both unless you really mean both.


LCD is 4*7*9.


{{{4*7*9(x/4+3x/7)=4*7*9(19/36)}}}
{{{63x+4*9*3x=7*19}}}
{{{(63+27*9)x=133}}}
{{{306x=133}}}
{{{x=133/306}}}              seems not reducible ___________(19*7)/(3*103)
