Question 951690
the sum of a number {{{x}}} times {{{7}}} and {{{3}}} equals {{{2}}}:

Let "some number" = {{{x}}}
therefore "the sum of a number  times {{{7}}}" = {{{7x }}}
and "{{{3}}}" = {{{7x +3}}}
equals {{{2}}}:{{{7x +3=2}}}

{{{7x+3=2}}}.......solve for {{{x}}}

{{{7x=2-3}}}

{{{7x=-1}}}

{{{x=-1/7}}}
