Question 146383


{{{-3(-x+4)=3x-12}}} Start with the given equation.



{{{3x-12=3x-12}}} Distribute.



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



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



{{{0x=-12+12}}} Combine like terms on the left side.



{{{0x=0}}} Combine like terms on the right side.



{{{0=0}}} Simplify.



Since this equation is <font size=4><b>always</b></font> true for any x value, this means x can equal any number. So there are an infinite number of solutions.
