-2 is the negative solution to the problem
For the first entry, given in the photo, we multiply the second equation by -2. This property is the multiplication property of equality (1).
Then, we add the two equations generated. (2) addition property of inequality.
Next, we divide both sides of the equation by 13. That is division property of inequality.
Moreover, we substitute the value obtained for y in the first equation. This is substitution property of equality.
Then, we simplify
Next, we add +3 to both sides of the equation in order to have an equation with only one side having a variable. That is addition property of equality.
Lastly, we divide both sides of the equation by 4. This is division property of equality.

Answer: There is a 30% chance Ricky will pull out a quarter
Step-by-step explanation:
This problem is quite simple, really. Okay, so first we're gonna figure out how many items in total there are. He has 3 quarters, 5 dimes, and 2 nickels. So 3+5+2 is equal to 10. Since there is 3 quarters out of the 10 different options, here is how many quarters are in the bag (aka the probability that Ricky will pull out a quarter): 3/10. 3/10 is the same thing as 30%, so there is a 30 percent chance Ricky will pull out a quarter.
