Answer:
Your answer is the first option, <u>(2,-1)</u>.
Step-by-step explanation:
All you have to do is plug the (x,y) values into both equations, then solve and see if they're true.
For the first equation, plug x (aka 2) and y (aka -1) into the places they belong.
2x + y = 3 would become 2(2) + (-1) = 3 after putting the values in the right spots.
Solve.
2(2) = 4.
4 + (-1) = 3
3 = 3.
That means that (2,-1) is the solution for the first equation, however it also needs to be true for the second. Do the same thing and plug the values in their designated spots.
y = x - 3 will become -1 = 2 - 3.
2 - 3 = -1.
So you're left with:
-1 = -1, which means again that (2,-1) is also the solution for that equation.
