Question 249966
I need help trying to figure this problem out....3/4=x/x+3
4X=3(x+3)   right???
this is where i am stumped


You're on the right track:


{{{3/4=x/(x+3)}}}
{{{3(x+3)=4x}}}
Now distribute the 3:
{{{(3*x)+(3*3)=4x}}}
Now solve for x:
{{{3x+9=4x}}}
{{{9=4x-3x}}}
{{{9=x}}}  ...same as... {{{x=9}}}
