Question 1104824
<pre>please solve 3x-x+2 x=1</pre>


Is this one expression and you want x=1, or is this one entire equation?

-

You are not presenting your problem well.
If you want x=1 to be used in the expression 3x-x+2 and evaluate it, then
{{{3*1-1+2}}}
{{{3-1+2}}}
{{{2+2}}}
{{{highlight(4)}}}


If this is not what you wanted to know, then present the problem and question more thoroughly and clearly.
