First multiple everything in the parentheses by
3
3 (2x+3)-6=
3(2x)+3(3)-6=
6x+9-6
then add together like terms
6x+9-6=
6x+3
so 6x+3 is your answer
I’m not rlly sure if i did it right & i’m sorry if i didn’t. i used the FOIL method
f= first to first
o=outer to outer
i=inner to inner
l= last to last
so it’d be
8b + 6b = 14b (f)
8b+ 8=16b(o)
-7+6b=-1b(i)
-7+8(l)
and then you add like terms so
[14b+16b-1b]+1
= 29b+1
