PLS HEL Which expression is equivalent to 4−a−a−a?

 " 4 − 3a " .

Step-by-step explanation:

" 4 − a − a − a " ;

        = 4 − 1a − 1a − 1a " ;

        =  ?  " ;

Combine the "like terms" :

         →   " − 1a − 1a − 1a " ;

               = (− 1a − 1a) − 1a ;

               = ( − 2a) − 1a ;

               =  − 3a ;

Now, bring down the "4" ;

  and rewrite the expression:

        →  " 4 − 3a " ;

which cannot be simplified further.

The answer is:  " 4 − 3a " .

Hope this is helpful!

 Best wishes to you!
