anyway the answer is PEMDAS
so the parenthasees is tricky -(3x-7) remember that -(3x-7) means -1(3x-7) so it equals -3x-(-7) 6x-(3x-7)+1 6x-3x+7+1 3x+8

We have to simplify 6x-(3x-7)+1. First we have multiply -1 (invisible -1 in front on parenthesis) by each argument inside the parenthesis. Lets do this 6x-(3x-7)+1=6x+(-1) (3x)+(-1) (-7)+1=6x-3x+7+1 Now we can simplify 6x with -3x and 7 with 1 to get 6x-3x+7+1=3x+8 - its our result

The expression 6 x − ( 3 x − 7 ) + 1 simplifies to 3 x + 8 . This is done by distributing the negative sign in the parentheses and then combining like terms. The final result is 3 x + 8 .
