i hope this helps!!

Answer 2

Put 4 where "a" is and do the arithmetic.

`12-(a)/(4)=12-(4)/(4)=12-1=11`

The value of the expression is 11.

This is very different from

`(12-a)/(4)=(12-4)/(4)=(8)/(4)=2`
In this latter case, parentheses are required when the expression is rendered using plain text: (12 -a)/4.
