Answer 2

Solving the System of Equations

To solve the system of equations: ``` 4x + 3y = 1 5x - y = -13 ```

We can use the method of substitution or elimination to find the values of x and y.

Method of Substitution

Let's solve the second equation for x: ``` 5x - y = -13 5x = y - 13 x = (y - 13) / 5 ```

Now substitute the value of x in the first equation: ``` 4((y - 13) / 5) + 3y = 1 (4y - 52) / 5 + 3y = 1 (4y - 52 + 15y) / 5 = 1 (19y - 52) / 5 = 1 19y - 52 = 5 19y = 57 y = 3 ```

Substitute the value of y back into the second equation to find x: ``` 5x - 3 = -13 5x = -10 x = -2 ```

Therefore, the solution to the system of equations is x = -2 and y = 3.

Note: The solution to the system of equations is x = -2 and y = 3.
