Question 427920
{{{ 5x+3+(-x)=2x+1+2x+3 }}}
Note that {{{2x + 2x = 4x}}}, so the right side is
{{{ 5x+3+(-x)=4x+1+3 }}}
Note that plus(minus) and minus(plus) = minus, so
{{{ 5x + 3 - x = 4x + 1 + 3 }}}
Now subtract {{{3}}} from both sides
{{{ 5x + 3 - 3 - x = 4x + 1 + 3 - 3 }}}
{{{ 5x - x = 4x + 1 }}}
{{{ 4x = 4x + 1 }}}
Subtract {{{4x}}} from both sides
{{{ 0 = 1 }}}
This is not true, so the original equation can't be true
If {{{1}}} is subtracted from the right side, then
The equation would be true for any {{{x}}}
