<u>Given:</u>
The two equations are 
and 
We need to solve the equations using elimination method.
<u>Elimination method:</u>
Let us multiply the equation by 5, we get;
---------(1)
Now, multiplying the equation by -2, we get;
--------(2)
Adding equations (1) and (2), we have;
Thus, the value of y is 3.
Substituting in the equation , we have;
Thus, the value of x is 4.
Hence, the solution of the system of equations is (4,3)
Therefore, Option A is the correct answer.
Answer:
Ellen is correct
Step-by-step explanation:
Roger:
The left side 20 does not equal to the right side 0.002 , which means that the given statement is false.
Ellen:

The net change between the given values of the variable is 6a - 6
<h3>How to determine the net change between the given values of the variable?</h3>
The given parameters are
g(x) = 6x
Where
x = 1 and x =a
Calculate g(1) and g(a)
So, we have
g(1) = 6 * 1
g(1) = 6
g(a) = 6 * a
g(a) = 6a
The net change between the given values of the variable is
Change = g(a) - g(1)
So, we have
Change = 6a - 6
Hence, the net change between the given values of the variable is 6a - 6
