Answer:
Jill make $18 on Wednesday
Step-by-step explanation:
Given :Jill is selling lemonade for $1.50 per cup on Tuesday.
To Find :On Wednesday she is selling the lemonade for the same price and sells 12 cups. How much money did she make on Wednesday?
Solution:
Jill is selling lemonade for $1.50 per cup on Tuesday.
Cost of 1 cup of lemonade = $1.5
Cost of 12 cups of lemonade = 
Hence She make $18 on Wednesday
X = 2y
2x + 2y = 24
So if x = 2y that means 2x = 4y. Which means that 2x + 2y = 24 can be written as 4y + 2y = 24. Simplified to 6y = 24. Now we need to get 1y so we divide both sides by 6, 6y/6 = y and 24/6 = 4. so y = 4. so x= 2y can be written as x = 8.
