lol does that really say "simplify"??!!

misty1212 · Answer

what idiot math teacher wrote this? means "solve for $n$"

misty1212 · Answer

if you multiply both sides by 5  you get $$4n-1=2n$$

misty1212 · Answer

so no your answer is not right

misty1212 · Answer

$$4n-1=2n\
2n-1=0\
2n=1$$ are the first three steps

misty1212 · Answer

i still can't believe it says "simplify"
who wrote this? FLVS? some other on line system?

skullpatrol · Answer

The question asks for the simplified form of the equation, 

which is the form of the equation in which the solution or solutions

can easily be seen. 

That is, an equivalent equation that has the same solution set as the original equation.

skullpatrol · Answer

You see, the answer is n = 1/2 because when n is replaced by 1/2 you get the true statement 1/2 = 1/2; 

which means the number 1/2 satisfies the original equation and thus is a solution or root of the equation.

This also shows why you can go back to the original equation and substitute 1/2 for n in it to check your work

to see if you still get a true statement.

$$\Huge \dfrac{4n}{5}—\dfrac{1}{5}=\dfrac{2n}{5}$$ 
$$\Huge \dfrac{4(1/2)}{5}—\dfrac{1}{5}=\dfrac{2(1/2)}{5}$$ 
$$\Huge \dfrac{2}{5}—\dfrac{1}{5}=\dfrac{1}{5}$$ 
$$\Huge \dfrac{1}{5}=\dfrac{1}{5}$$
