Answer:
<h3>
( - 1 , - 1 )</h3>
Option D is the correct option.
Step-by-step explanation:
y = - 2x - 3 → Equation ( i )
y = 3x + 2 → Equation ( ii )
Using elimination method
y + 2x = - 3
y - 3x = 2
---------------------
5x = - 5
Divide both sides of the equation by 5

Calculate

Again, Putting the value of x in equation ( ii ) in order t get the value of y

plug the value of x

Any expression multiplied by ( - 1 ) equals it's opposite

Calculate

Therefore, The possible solution of the system is the ordered pair ( x , y )

-----------------------------------------------------------------------
Check if the given ordered pair is the solution of the system of equation


Simplify the equation


Since all the equalities are true, the ordered pair is the solution of the system.
<h3>
( x , y ) = ( - 1 , - 1 )</h3>
