This is just the answer digitally i cant explain the process
 
        
        
        
 3x - 2y = 8 +
 ===》 46x = 16 
43x + 2y = 8
 x = 16/46
 x = 8/23
______________________________
3x - 2y = 8 
3(8/23) - 2y = 8 
24/23 - 2y = 8 
2y = 24/23 - 8
y = 12/23 - 4 
y = 12/23 - 92/23
y = - 80/23
 
        
             
        
        
        
If I could get more context then that would help. Because an exponent being an odd number doesn’t do anything, so it could be either a negative or a positive
