Answer:
Our system of equations is:

And its solution is:

Explanation:
First, we'll fill out the second equation.
We'll choose a value for x. In this case, we'll work with:

Now, we'll chose 2 as a coefficient for x and 3 as the independent term. This way, we'll have the equation:

And since we've established that x = 1,

From now on, we know that the solution to our system is:

Now, we'll work on the first equation. We'll chose 4 as a coefficient for x and 5 as a coefficient for y. This way, we'll have the expression:

And since we already know the values of x and y, we'll have that:

Therefore, our first equation is:

Therefore, we can conclude that our system of equations is:

And its solution is:
