Answer:
23) x= 3, y = 4
24) Any (x,y) values where x = 1.5 - 2y
Step-by-step explanation:
For the first system(23), it goes like this
[1 2 | 7]
[2 1 | 8]
We need to do L2 = L2 - 2L1, so now it is
[1 2   | 7]
[0 -3 |-6]
So, now we have:
-3y = -6 *(-1)
3y = 6
y = 2
x + 2y = 7
x + 4 = 7
x = 3
Now for system 24, we have:
[-1 2 | 1.5]
[2 -4| 3]
We do L2 = L2 + 2L1, so we have:
[-1 2 | 1.5]
[0 0| 0]
So there are infinite solutions for this system. The solution for this system will be each (x,y) pair where x = 1.5 - 2y. 
 
        
             
        
        
        
Let's multiply each of the four squares, one by one.
In blue, we see the dimensions are x by x.  x times x = x^2
In pink, we see the dimensions are 9 by x.  x times 9 = 9x
In green, the dimensions are x by 3.  3 times x = 3x
And finally, yellow's dimensions are 3 by 9.  3 times 9 = 27
We can now just add all these areas to find the total area:
x^2 + 12x + 27
 
        
                    
             
        
        
        
X and y are points that help u place other points
