ok I think I understand you

Eddie gets 300+(400/3) dollars   and   joe and John both get (400/3) dollars

The extra 300 that Eddie gets it 3/7 of the total so that should attract 3/7 of the debt

$${\frac{{\mathtt{3}}}{{\mathtt{7}}}}{\mathtt{\,\times\,}}{\mathtt{300}} = {\frac{{\mathtt{900}}}{{\mathtt{7}}}} = {\mathtt{128.571\: \!428\: \!571\: \!428\: \!571\: \!4}}$$    that is $128.57

The rest of the debt is divided equally 3 ways        

rest of debt =    $${\mathtt{300}}{\mathtt{\,-\,}}{\mathtt{128.57}} = {\mathtt{171.43}}$$

$${\frac{{\mathtt{171.43}}}{{\mathtt{3}}}} = {\mathtt{57.143\: \!333\: \!333\: \!333\: \!333\: \!3}}$$

So Eddie pays    $${\mathtt{128.57}}{\mathtt{\,\small\textbf+\,}}{\mathtt{57.14}} = {\mathtt{185.71}}$$   dollars

John and Joe pay   $57.14

check:   $${\mathtt{185.71}}{\mathtt{\,\small\textbf+\,}}{\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{57.14}} = {\mathtt{299.99}}$$       

There you go ...   someone better cough up the extra 1 cent :)

There are lots, wqhat do you want me to choose from?

You cannot post pics unless you are a member.   :/

Great answer DarkbBlaze347  

There is no graph - you have to be a member to post pictures.

1/x=5/x-4

If you mean

$$\\\frac{1}{x}=\frac{5}{x}-4 \qquad then\\\\
\frac{1}{x}-\frac{5}{x}=-4\\\\
\frac{1-5}{x}=-4\\\\
\frac{-4}{x}=-4\\\\
\frac{4}{x}=4\\\\
\frac{4}{x}=4\\\\
x=1$$

Why would anyone not like maths???

$$\\y=\sqrt{4-x}-3\qquad x\le4 \qquad y\ge-3 \\\\
y+3=\sqrt{4-x}\\\\
(y+3)^2=4-x\\\\
x=4-(y+3)^2\\\\
x=4-(y^2+6y+9)\\\\
x=4-y^2-6y-9\\\\
x=-y^2-6y-5\\\\
Inverse\;\;function\\\\
y=-x^2-6x-5 \qquad where \;\;\; x\ge-3\\\\$$

Here is the graph

$$\\(\frac{1}{4})^{3/2}\\\\
=\frac{1}{4^{3/2}}\\\\
=\frac{1}{(4^{1/2})^3}\\\\
=\frac{1}{(\sqrt{4})^3}\\\\
=\frac{1}{(2)^3}\\\\
=\frac{1}{8}\\\\$$
