Question 217617


{{{5P-8=1+5P-9}}} Start with the given equation.



{{{5P-8=5P-8}}} Combine like terms on the right side.



{{{5P=5P-8+8}}} Add {{{8}}} to both sides.



{{{5P-5P=-8+8}}} Subtract {{{5P}}} from both sides.



{{{0P=-8+8}}} Combine like terms on the left side.



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



So there are an infinite number of solutions.
