Answer: x = 5, y = 2

Explanation:

To solve the system of linear equations using the elimination method, we'll eliminate one variable by adding the two equations together. Let's start:

Original equations:

-5x + 3y = -19

-x - 3y = -11

Adding the two equations eliminates the variable "y":

(-5x + 3y) + (-x - 3y) = -19 + (-11)

-5x + 3y - x - 3y = -19 - 11

-6x = -30

Dividing both sides of the equation by -6:

-6x / -6 = -30 / -6

x = 5

Now that we have the value of x, we can substitute it back into one of the original equations to find y. Let's use the second equation:

-x - 3y = -11

-5 - 3y = -11

Simplifying the equation:

-3y = -11 + 5

-3y = -6

Dividing both sides of the equation by -3:

-3y / -3 = -6 / -3

y = 2

Therefore, the solution to the system of equations is x = 5 and y = 2.
