Question 22448
2 1/6-h/18=1/3

First make 2 1/6 an improper fraction;
{{{13/6}}}-{{{h/18}}}={{{1/3}}}
subtract {{{13/6}}} from both sides;
{{{13/6}}}-{{{h/18}}}-{{{13/6}}}={{{1/3}}}-{{{13/6}}}
-{{{h/18}}}={{{2/6}}}-{{{13/6}}}
-{{{h/18}}}=-{{{11/6}}}
Now multiply both sides by 18;
-{{{h/18}}}(18)=-{{{11/6}}}(18)
-h=-{{{198/6}}}
-h=-33
You don't want to leave the variable as -, so you multiply each side by -1;
h=33
Hopr you understand
