This is the commutative property (of addition, but this applies to multiplication as well)
It doesn't matter which order the numbers are added in, the same result will be achieved.
1+2 = 2+1
2*4 = 4*2
        
                    
             
        
        
        
     SUM:                x + y = 288
DIFFERENCE:   +  <u>x - y =  48 </u>
                             2x     = 336
                              x      = 168
  SUM: x + y = 288  →   (168) + y = 288   →   y = 120
Answer: 120, 168
