Question 676874


If the problem it {{{9k=10-k}}}, and if {{{-1}}} represent the {{{k}}}, than we have

{{{9(-1)=10-(-1)}}}

{{{-9=10+1}}}

{{{-9<>11}}}

If the problem it {{{9k=10-k}}}, and if {{{1}}} represent the {{{k}}}, than we have

{{{9(1)=10-(1)}}}

{{{9=10-1}}}

{{{9=9}}}....so,{{{1}}} represents the {{{k}}}
