Final answer:

The solution to the system of equations y = 3x + 19 and y = 5x + 33 is found by setting them equal to each other and solving for x, which is -7, then plugging x back into either equation to solve for y, which is -2. Therefore, the solution is (x, y) = (-7, -2).

Step-by-step explanation:

When solving the system of equations given by y = 3x + 19 and y = 5x + 33, you can use either substitution or elimination. Since they are both in y = mx + b form, it is straightforward to use substitution.

Set the two equations equal to each other because they both equal y:

3x + 19 = 5x + 33

Solve for x:

19 - 33 = 5x - 3x

-14 = 2x

x = -7

Now, substitute x back into either of the original equations to solve for y:

y = 3(-7) + 19

y = -21 + 19

y = -2

Therefore, the solution to the system of equations is (x, y) = (-7, -2).
