Don't miss that second to last one. I did it wrong. It was "Subtraction property of equality."

1.) 6x-8y=18, 2x+8y=6 → Multiplication property of equality

2.) 8x=24 → Addition property of equality

3.) x=3 → Division property of equality

4.) 3(3)-4y=9 → Substitution property of equality

5.) 9-4y=9 → Simplify

6.) -4y=0 → Subtraction property of equality 

7.) y=0 → Division property of equality

In the given problem it is already given that the total number of jerseys are 50. Out of them 35 are mid sized jerseys. We can see that all required information's are already present in the problem.
Total number of medium sized jerseys = 35
Total number of jerseys = 50
Percentage of medium sized jerseys = (35/50) * 100
                                                             = 35 * 2
                                                             = 70
So 70% of the jerseys are mid sized jerseys. This is the only way to find the percentage of mid-sized jerseys. I hope this method is clear to you and you can attempt any problem like this in the future.

Answer:

Example to help you out!

May rides her bike the same distance that leah walks. may rides her bike 10 km/h faster than leah walks. if it takes may 1 h and leah 3 h to travel that distance, how fast does each travel?

----------------------------------------

May DATA:

time = 1 hr. ; rate = x+10 mph ; distance = rt = (x+10)*1 mi

--------------------

Leah DATA:

time = 3 hr. ; rate = x mph ; distance = rt = 3x mi

-----------------------

Equation:

distance = distance

x+10 = 3x

2x = 10  

x = 5 mph (Leah's rate)

x+10 = 15 mph (May's rate)
