The answer is: 1 + 5a ; or, 5a + 1 .
______________________________
Given the expression:
______________________________
1 + 10a − 5a ;
________________
→ We identify the "like terms" ;
___________________________
→ which are "10a" and ( "-5a") ;
____________________________
→ 10a − 5a = 5a ;
_________________________________
→ 1 + 5a ; is the most simplified; or write the expression as: 5a +1 .
