<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.

First, set the coordinate points on a graph, and joint them to form a graph
By looking at the graph we can see that:
width : 3
length: 6
Area of a rectangle : Length x width : 6 x 3 = 18
