Please need help with 2 problems of algebra. I will give you 30 points if you help me.

Answer 1

For number 7 I got the answer of 0. You do parentheses first so (12-4)=8 And then the brackets [24/8] =3 and then subtract 3 from that and get 0
The answer for the second picture is 4. You add 20 + 8=28 and then 4+3=7 and then divide 28 by 7 and get 4

Answer 2

Hello ,
1/
= 7 . [24 : 8 ] - 3
= 7 . 3 - 3
= 21 - 3
= 19 .

2/
= 28 : 4 + 3
= 7 + 3
= 10 .
