Answer for brainliest

Answer 1

Answer:

(-4, -1) (see below)

Step-by-step explanation:

Substitution means that you actually replace, or "substitute," the value of the variable in.

Here, y = -1, so -3x - 8y = 20 can be written as:

-3x - 8 (-1) = 20

We can now solve for x:

-3x + 8 = 20

-3x = 12

x = -4

Putting this into (x, y) format equals:

(-4, -1)
