Solve the system by substitution.<br> -8x - y = 30<br> -2y = x
masya89 [10]

Answer:

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
