Question 946682
Assume the problem is:
{{{-3/4}}} + {{{1/2}}}x = {{{2/3}}}
we can get rid of all those annoying fraction by multiplying by 12
12*{{{-3/4}}} + 12*{{{1/2}}}x = 12*{{{2/3}}}
Cancel the denominators and we have
3(-3) + 6x = 4(2)
-9 + 6x = 8
6x = 8 + 9
6x = 17
x = {{{17/6}}}

You can check this with substitution
{{{-3/4}}} + {{{1/2}}}*{{{17/6}}} = {{{2/3}}}
