There are 3 ways of solving a simultaneous problem, substitution method, elimination method and Gauss-Jordan method. I'm gonna use the substitution method since it's easier and i think it would suit your level more.
First let's try solving for y since it's easier to start with. 
Firstly we have to find an equation for x:

Great, now we can use the substitution method to find the value of y using the first equation:

Now we know that y=1 we can solve the first equation we made:

And the answer is 
Double check:

And that's our final answer! (4,1)
 
        
             
        
        
        
Answer: 
<u>Do Keep Change Flip (KCF)</u>
Keep: 5/6
Change: ÷ into ×
Flip: 3/1 into 1/3
Your new problem should be: 5/6×1/3
<u>Multiply</u>
5/6×1/3=5/18
