If you would like to solve y = x - 4 and 2 * x + y = 5, you can do this using the following steps:
y = x - 4
2 * x + y = 5
_____________
2 * x + (x - 4) = 5
2 * x + x = 5 + 4
3 * x = 9     /3
x = 9 / 3 
x = 3
y = x - 4 = 3 - 4 = -1
The correct result would be x = 3 and y = -1.

Answer:
-1 3/4 =x 
Step-by-step explanation:
-3 1/2= 1/2x+1/2x+x
Combine like terms
-3 1/2 = 2x
Change to an improper fraction
- ( 2*3+1)/2 = 2x
-7/2  = 2x
Multiply each side by 1/2
-7/2 *1/2 = 2x* 1/2
-7/4 = x
Changing to a mixed number
-4/4 -3/4 =x
-1 3/4 =x 
 
        
             
        
        
        
Answer:

Step-by-step explanation:
3 1/2 x 1 2/3 = 35/6 
6 x 5 + 5 = 35/6
 
        
             
        
        
        
Y = 2, so C. Have a good day :)
