Answer:
There are 8 numbers.
4 of the numbers are even ( 2, 4, 6, 8)
The probability is the number of even numbers over the total numbers:
4/8 which reduces to 1/2.
The answer is 1/2
Answer: D
Step-by-step explanation:

Let's take one of the equations and solve for a variable to use the substitution method.

Now replace this in the first equation.

Separate the terms.

Solve 20/5

Subtract 4 from both sides to isolate y.


Solve the difference.



Multiply by the reciprocal or the inverted fraction that is next to y to isolate it.


Now, in order to find x, replace y in any of the two equations.
