Question 152918
Can you explain what a no solution equation with a Variable is? Can you give me a couple of examples.
<pre><font size = 4 color="indigo"><b>
It's one that is equivalent to a false equation 
without a variable.

Example 1:

 {{{x+3=x-7}}}

Subtract x from both sides:

 {{{3=-7}}}

That is a false equation without a variable.

--------------------

Example 2:

{{{2x+5(x+3)=3x-2(5-2x)}}}

Remove the parentheses:

{{{2x+5x+15=3x-10+4x}}}

Combine like terms:

{{{7x+15=7x-10}}}

Subtract {{{7x}}} from both sides

{{{15=-10}}}

That's a false equation with no variables.
