Question 669625
{{{3(g-1)+7=3g+4}}} Start with the given equation.



{{{3g-3+7=3g+4}}} Distribute.



{{{3g+4=3g+4}}} Combine like terms on the left side.



{{{3g=3g+4-4}}} Subtract {{{4}}} from both sides.



{{{3g-3g=4-4}}} Subtract {{{3g}}} from both sides.



{{{0g=4-4}}} Combine like terms on the left side.



{{{0g=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 g value, this means g can equal any number. 


So there are an infinite number of solutions.
