Answer:
(14, -2)
Step-by-step explanation:
To solve by using substitution, begin by solving for a variable in the first equation. Let's solve for x:

Now we know what <em>x</em> equals. Let's substitute this into the second equation:

We can then simplify:
 Given equation
 Given equation
 Combine y terms
 Combine y terms
 Add 2
 Add 2
 Divide by -11
 Divide by -11
So, we now know the value of y = -2.
To find the value of X, we can substitute the value of Y into one of the equations. Let's use the first one:

 Substitute for y
 Substitute for y
 Distribute 8
 Distribute 8
 Add 16
 Add 16
So, we now know the value of x = 14.
Therefore, we know a solution to the system of equations is (14, -2).
 
        
             
        
        
        
Answer:
720 - 1 x 2 x 3 x 4 x 5 x 6 
0.14% - 1/170
 
        
             
        
        
        
A' = (-2, 1)
B' = (1, 0)
C' = (-1, 0)
        
                    
             
        
        
        
I belive the answer would be....
49.5-37.5=12
2•12=24
