Answer:
2 3/4
Step-by-step explanation:
Make 1/3 a reciprocal: 3/1 = 3 then turn the division symbol into a multiplication symbol the multiply and simplify.
 
        
                    
             
        
        
        
2n + 5 = 27
2 * 11 + 5 = 27
22 + 5 = 27
27 = 27
11 is the solution to this equation.
        
             
        
        
        
If your amount of fencing was 247.10 then you would divide that by 4 and multiply your result by 36 to find the amount of money needed to build a fence, your result is $2,196, now of course you have have more than 4 feet left but since the problem asks every 4 feet of fencing costs $36, I’m going to assume that if you have more than 4 but less than 8 you get that for free
        
             
        
        
        
You can use the substitution method for this problem
Since -3y+8=x you can 
Use the equation -7(-3y+8) -6y=4
You then distribute and solve
21y-56-6y=4
15y=60
Y=4
You then plug y into one of the original equations
X=-12+8
X=-4
(-4,4)
        
             
        
        
        
The simplified version would be 8nx - 7p - 6x
