Given:
There are given the equation:

Explanation:
From the equation (1):
Put the value of x into the equation (2):
So,
From the equation (2):

Now,
Put the value of y into the equation (1):
So,
From the first equation:

Final answer:
Hence, the ordered pair of the solution is shown below:
Y=10
explanation:
-4•2= -8
2•4=8
-8+8=0
y=10
Answer:
the answer you have chosen is right.
Step-by-step explanation:
A rational number can be written as a simplified fraction, and or is a recurring or finite decimal. That is the only number that can be properly written according to the rules I just stated.
When we prime factorize, we get 180=2^2*3^2*5. So therefore there are 3 prime factors that make up 180.
