Question

Please for the love of god someone help me I cant stop crying
Use the substitution method to solve the system of equations
y=-8x
4x-y=3
a) (1/2,-1)
b) (1/4,-2)
c) (1/2,-4)
d) (1/4,-4)

Answer 1

Answer:

Cry no more :) The answer is B) 1/4, -2

Step-by-step explanation:

y = -8x

Plug in your x (1/4), and y(-2)

-2 = -8(1/4)

-2 = -2

Again, plug in your x and y in the second equation

4x-y = 3

4(1/4) + 2 = 3

- Note: -2 becomes a positive 2 because 2 negatives become a positive

1 + 2 = 3

3 = 3
