Question 1023916
{{{5 - 3x = 2x + 9}}}, if {{{3x}}} is added to the both sides of the equation, we have

{{{5 - 3x +3x= 2x +3x+ 9}}}........simplify

{{{5 - cross(3x) +cross(3x)= 5x+ 9}}}

{{{5 = 5x+ 9}}} if {{{-9}}} is added to the both sides of the equation, we have

{{{5-9 = 5x+ 9-9}}}........simplify

{{{-4 = 5x+ cross(9)-cross(9)}}}

{{{-4 = 5x}}}....... both sides of the equation divide by {{{5}}}

{{{-4/5 = 5x/5}}}

{{{-4/5 = cross(5)x/cross(5)}}}

{{{-4/5 = x}}}
