Standard form: ax+by=c
With standard form there are a few rules One being ax and by cannot be fractions. Two being ax has to be positive.
Now ill explain the problem.
y=-1/2x-5 ↔ You will need to multiply the whole problem by 2 which will leave you will this 2y=-2x-10
Next you will need to move x over to the y side which will look like this 2x+2y=-10 (your answer)
Now you might be asking where the - went that was in front of the x term. Another rule is when you move across the equal sign you change the sign.

Answer:
You have told us that there is $450 in Josie's bank account, and she does not make any later deposits or withdraws. You have also told us that the gym deducts $35.20 every one month in fees.
Explanation:
The answer is really easy to find. All you have to do is subtract 35.20 from 450. The problem asks for the amount of money that Josie has in her account at the end of the month - the same month that she put $450 into her account.
Solve:
450 - 35.20
= 414.80
Josie has $414.80 in her bank account at the end of the month.

Answer:
let the number of adult tickets = x
