x = 1/4

y = -2

Step-by-step explanation:

Answer 2

x = 1/4

y = -2

______________

Known :

y = -8x

4x - y = 3

Asked:

Use the substitution method to solve the system of equations ?

Answered:

Substitution y

4x - y = 3

4x - (-8x) = 3

4x + 8x = 3

12x = 3

x = 3/12

x = 1/4

Substitution x

4x - y = 3

4(1/4) - y = 3

4/4 - y = 3

1 - y = 3

-y = 3 - 1

-y = 2

y = -2
