Question 158516
{{{1/5 + 1/x = 1/2}}} --------------> working eqn
{{{1/x=1/2-1/5}}}, combine similar terms
{{{1/x=(5-2)/10}}}, get LCD
{{{1/x=3/10}}}, cross multiply
{{{3x=10}}}, divide 3 to isolate x:
{{{cross(3)x/cross(3)=10/3}}}
{{{x=10/3}}} or "3-1/3"
Check, go back working eqn:
{{{1/5+(1/(10/3))=1/2}}}
{{{1/5+3/10=1/2}}}
{{{(2+3)/10=1/2}}}
{{{5/10=1/2}}}
{{{1/2=1/2}}}
thank you,
