When simplifying this, we would have to take this little by little in serious steps and not only this, but to also take notice of the use of <u>
pemdas</u>
 and to make sure that we take each step carefully.
We first would <u>

 simplify the following:
 
 
        
        
        
First write the equation 
3/n = 5 
Multiply both sides by n
3/n * n = 5 * n
Simplify 
3 = 5 * n
Divide both sides by 5
3/5 = 5 * n/5
Simplify
3/5 = n
Divide 
0.6 = n
So 3/0.6 = 5
        
             
        
        
        
X-y=3=>x=3+y
X+2y=-6
=========
3+y+2y=-6
3+3y=-6
3y=-6-3
3y=-9
y=-3
X+2y=-6
X+2(-3)=-6
X-6=-6
X=0
