1 answer:
Answer:
y= 3
Step-by-step explanation:
1. plug in 7 - 2y for X in 2x = y = 5 it would look like this 2(7-2y) = y= 5
2. distribute the 2 with what is in the parenthesis. remember PEMDAS!! it would be 14 - 4y + y = 5
3. get the y alone. to do this subtract 14 from both sides. you will have
-4y + y = -9
4. combine the Y. you will get -3y = -9 (remember there is a 1 in front of alone variables that is how i got - 3)
5. divide to get the Y alone. that will be -9/-3 which is 3
your final answer: Y= 3
hope this helped :)

Step-by-step explanation:
Let s equal the cost per shirt.
First, we are going to multiply the cost of one shirt to the sale of 25%
0.25s
Second, we are going to multiply by 3 since you are buying 3 shirts.
* 3
Put together.
0.25s * 3
Best of Luck!
(ab)/2 = (3 * 6)/2 = 18/2 = 9
