Solve for X
7x-18+9*4/2= 42
What is x=6
7x-18+9*4/2=42
First multiply 9 and 4
7x-18+36/2=42
then divide 36 by 2
7x-18+18=42
next add -18 and 18
7x=42
finally both sides by 7
x=6

first parenthese: 15/24 + 16/24 = 31/24 = 1 7/24
second parenthese: 11/4 *⅓ = 11/12
next subtract these 31/24 - 11/12
RJ subscribes to a live-streaming website. It costs x amount of money per month but then adds 5.50$ for every 6 live streams watched. For the first month, RJ had to pay 35.75$. If he watched 15 live streams, how much would it cost monthly if you didn’t watch them?
What is $22
15/6=2.5
2.5*5.50 = 13.75.
35.75-13.75 = $22
