Answer:
<h2>( 2 , - 3 )</h2>Step-by-step explanation:
Using elimination method:
2x - y = 7
3x + y = 3
--------------
5x = 10
Divide both sides of the equation by 5
Calculate
Now, substitute the given value of X in the equation
3x + y = 3
Multiply the numbers
Move constant to R.H.S and change it's sign
Calculate
The possible solution of this system is the ordered pair ( x , y )
<h3>( x , y ) = ( 2 , -3 )</h3>---------------------------------------------------------------------
Check if the given ordered pair is the solution of the system of equation
Simplify the equalities
Since all of the equalities are true, the ordered pair is the solution of the system
<h3> ( x , y ) = ( 2 , - 3 )</h3>Hope this helps..
Best regards!!
