Step 2: Write the two new equations
as a system
Step 3: Substitute the value for x and z
into one of the original equations
3 =11

The solution (5, 1, -2)
Step-by-step explanation:
Answer:
B: 0
Step-by-step explanation:
Note that (3, 1) satisfies the equation y = 2x - 5:
1 = 2(3) - 5
1 = 6 -5 = 1
Therefore, the distance between this point and this line is zero.
B is the correct answer.

Explanation:
You can check your answer by making sure that each of the primes you found is actually a prime. (Compare to a list of known primes, for example.) After you have determined your factors are primes, multiply them together to see if the result is 73. If so, you have found the correct prime factorization.
__
<em>Additional comment</em>
73 is prime, so its prime factor is 73.
73 = 73
You simply divide 678 by 3 and get 226.
