solve equation.. i continually keep getting this problem wrong

Since 5-2=3, saying x/3=x/3 isn't really saying anything. Multiply each side by 3/1 if you don't believe me. Did you copy it down correctly?

ok so for this you do
you multiple both sides by 3
so you have
then go on from there

Brit's math is incorrect.
In contrast to Averageman, I am assuming that your equation is really:
x/3 = x/5 - 2
Not x/3 = x/(5-2)
Multiply both sides by 15 to get rid of both denominators.
5x = 3x - 30
Subtract 3x from both sides.
2x = -30
Divide both sides by 2.
x = -15
