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:
this is an example
Step-by-step explanation:
There are a few different ways to approach this problem, including the following two methods.
1) Find 20% of the original price, then subtract that amount from the original price.
To find a percentage of a number, you multiply the number by the percentage. (You are finding a part of a whole.)
20% = 20/100 = 1/5 or 20% = 0.20
Original Price: $24 Find 20% of $24. (Note: "of" is taking part of a whole, so you multiply.)
0.20 x 24 = 4.80 This is the mark down, or the amount you subtract from original price.
Sale Price = Original Price - Mark Down
= 24.00 - 4.80
= 19.20
2) If you save 20%, you are still paying 80%. (100-20 = 80) Therefore the sale price is 80% of the original price.
80% = 80/100 = 4/5 or 80% = 0.80
Sale Price = 80% of Original Price
= 0.80 x 24
= 19.20
Answer: 1= ( 13 + 4g )
2= ( 4(10) + 13 )
3= ( 13 + 4(10) )
4= ( 53 )
5= ( 21 )
