Answer: OPTION B.
Step-by-step explanation:
Given the following System of equations:

You can use the Elimination Method to solve it. The steps are:
1. You can mutliply the second equation by -3.
2. Then you must add the equations.
3. Solve for the variable "y".
Then:

4. Now that you know the value of the variable "y", you must substitute it into any original equation.
5. The final step is to solve for "x" in order to find its value.
Then:

Therefore, the solution is:

Answer:
Length = 12 feet
Width = 30 feet
Step-by-step explanation:
Let l be the length of the garden and let w be the width:
We have system of equations
2w + l = 54
l = 2w + 6
We substitute 2w + 6 for l
2w + 2w + 6 = 54
4w + 6 = 54
4w = 54 - 6
4w = 48
w = 48/4
w = 12 feet
Width(w) = 12 feet
We find the Length
l = 2w + 6
l = 2(12) + 6
l = 24 + 6
I = 30 feet
Given:
Consider the below figure attached with this question.
The linear equation is:

To find:
The values to complete the table of ordered pairs for the given linear equation.
Solution:
We have,

Substituting
in the given equation, we get



So, the value for first blank is -8.
Substituting
in the given equation, we get




So, the value for second blank is 3.
Substituting
in the given equation, we get



So, the value for third blank is -4.
Therefore, the required complete table is:
x y
0 -8
3 -2
2 -4
