Answer:
Ordered pair: (3,6)
Explanation:
So, first off since we are using substitution we are going to plug the first equation into the second one.
5x-2x=9
That can then simplify into:
3x=9
Then you want to divide 3 from 3x and 9
That then leaves you with:
X=3
Then you are going to plug the x into a equation.
I am going to use the first one.
Y=2x3
That can simplify into y=6
That would be (3,6) in ordered pair form.
You can check (3,6) into the second equation
1. 5x3 - 6 =9
2. 15-6=9
3. 9=9 which is true!
