Which expression is equivalent to 7a - 8 - 12a + 4?

I need step by step

First of all, add up the expressions with the same variables and the numbers.

7a-8-12a+4

=7a-12a-8+4

=-5a-4

or

=-(5a+4)

Both of them can be counted ans equivalent expression since all three of them works the same. Only the expression(way of writing) seems different.

_ 5a - 4

Step-by-step explanation:

=7a + − 8 + −12a + 4

=( 7a + −12a ) + (− 8 + 4 )

=− 5a - 4  Answer!
