Question 106871
{{{(-7x+2)/3 + 4/3 = -7x/2}}}

If we multiply both sides by 6,

{{{6(-7x+2)/3 + 4/3 =6( -7x/2)}}}
{{{2(-7x+2)+2(4)=3(-7x)}}}
{{{(-14x+4)+8=-21x}}}
{{{-14x+(4+8)=-21x}}}
{{{-14x+12=-21x}}}
{{{-14x+21x+12=-21x+21x}}}
{{{7x+12=0}}}
{{{7x+12-12=0-12}}}
{{{7x+0=-12}}}
{{{7x=-12}}}
{{{x=-12/7}}}


Since the equation is true if and only if {{{x=-12/7}}}, this is a conditional equation.
