Answer:

(-1, -5)

Step-by-step explanation:

If we use the graph, we can see that the two lines intersect at (-1, -5)

Another way to solve this is the substitution method

5x = 4x - 1

Subtract 4x from both sides

5x = 4x - 1

- 4x    - 4x

x = -1

Plug in the new x into one of the original equations. Let's use the top one

y = 5(-1)

y = -5

We got

x = -1

y = -5
