Question 256143
{{{x^2=7x}}} Start with the given equation.



{{{x^2-7x=0}}} Subtract 7x from both sides.



{{{x(x-7)=0}}} Factor the left side




Now set each factor equal to zero:

{{{x=0}}} or  {{{x-7=0}}} 


{{{x=0}}} or  {{{x=7}}}    Now solve for x in each case



So our answers are 


 {{{x=0}}} or  {{{x=7}}}
