Question 1047258

{{{2 + 11b = 8b + 15}}}
{{{ 11b -8b=  15-2}}}
{{{ 3b=  13}}}
{{{ b=  13/3}}}

{{{b}}}={{{4}}}{{{ 1/3}}}

 to check this problem start with given equation

{{{2 + 11b = 8b + 15}}} substitute {{{13/3}}} for {{{b}}}, will be easier to use fraction then mix number {{{4}}}{{{ 1/3}}}


{{{2 + 11(13/3) = 8(13/3) + 15}}}

{{{6/3 + 143/3 = 104/3 + 45/3}}}

{{{149/3 = 149/3 }}}-> left and right sides are equal which confirms our solution is correct
