{{{ 6c/11 + 9/2 = 3}}}

{{{ 6c/11 + 9/2 -9/2= 3-9/2}}}


{{{ 6c/11= 3-9/2}}}


{{{ 6c/11= 6/2-9/2}}}


{{{ 6c/11= -3/2}}}....cross multiply


{{{ 2*6c= -3*11}}}


{{{ 12c= -33}}}


{{{ c= -33/12}}}


{{{ c= -2.75}}}


check:



{{{ 6c/11 + 9/2 = 3}}}


{{{ 6(-2.75)/11 + 9/2 = 3}}}


{{{ -16.5/11 + 9/2 = 3}}}


{{{ -1.5 + 4.5= 3}}}
