Question 121338


{{{1/2 (4d - 2 )= d +5}}}....multiply both sides by {{{2}}}


{{{2(1/2) (4d - 2 )= 2*d + 2*5}}}....

{{{cross(2)(1/cross(2)) (4d - 2 )= 2d + 10}}}....

{{{1(4d - 2 )= 2d + 10}}}....

{{{4d - 2 = 2d + 10}}}....move {{{2d}}} to the left and {{{-2}}} to the right

{{{4d - 2d = 2 + 10}}}....

{{{ 2d =  12}}}............divide both sides by {{{2}}}

{{{ 2d/2 =  12/2}}}............

{{{ d =  6}}}............
