Question 693002
{{{12-h=-h+3}}} Start with the given equation.



{{{-h=-h+3-12}}} Subtract {{{12}}} from both sides.



{{{-h+h=3-12}}} Add {{{h}}} to both sides.



{{{0h=3-12}}} Combine like terms on the left side.



{{{0h=-9}}} Combine like terms on the right side.



{{{0=-9}}} Simplify.



Since this equation is <font size=4><b>NEVER</b></font> true for any h value, this means that there are <font size=4><b>NO</b></font> solutions.
