Question 895424
{{{ -8 + 7x - 2 = 3x + 4 + 2x }}}
Get all the terms with an {{{ x }}} on
the left side, and the constant terms 
on the right side
-------------------
First, add {{{ 3x }}} and {{{ 2x }}} on
the right side
{{{ -8 + 7x - 2 = 5x + 4  }}}
Now add the {{{ -8 }}} to the {{{ -2 }}}
on the left side
{{{ -10 + 7x = 5x + 4 }}}
Now subtract {{{ 5x }}} from both sides
{{{ -10 + 2x = 4 }}}
Now add {{{ 10 }}} to both sides
{{{ 2x = 14 }}}
Now divide both sides by {{{ 2 }}}
{{{ x = 7 }}} answer
-----------------------
You can check this by plugging in
a {{{ 7 }}} where you see an {{{ x }}}
in the original equation
{{{ -8 + 7x - 2 = 3x + 4 + 2x }}}
{{{ -8 + 7*7 - 2 = 3*7 + 4 + 2*7 }}}
{{{ -8 + 49 - 2 = 21 + 4 + 14 }}}
{{{ 49 - 10 = 35 + 4 }}}
{{{ 39 = 39 }}}
OK
