Fletcher Nolan · Answer 1

Solution: (-4, 2), x = - 4 and y = 2

Step-by-step explanation:

-8x - y = 30

-2y = x

Substitute for x

-8 * (-2y) - y = 30

16y - y = 30

15y = 30

y = 30/15 = 2

Then x = - 2y = - 2 * (2) = - 4

Solution: (-4, 2), x = - 4 and y = 2

Solve the system by substitution.-8x - y = 30-2y = x

Solve the system by substitution.
