Answer:
<em>Addition Property of Equality</em>
Step-by-step explanation:
<u>System of Equations</u>
When two equations are given and two variables are unknown in both equations, then we can solve the system in several ways.
One method consists in adding both equations term by term and eliminate one of the variables. That property is called the addition of equalities. Let's consider the equations given in the problem:

If we add both equations, we have

Simplifying

By adding both equations we managed to eliminate the variable y and could easily find the value of x

Answer: Addition Property of Equality
Answer:
first what you do is divide two and then for and then after you divide them together you can get your number so I'm going to show you example how to do it
Step-by-step explanation:
first divide 4 / 2 and then you can get your answer after you divide that
Answer:
no
Step-by-step explanation:
C=pid
Since d=9m and pi=3.142, C=3.142*9m=28.278
Rounded to 1 decimal point =28.3
