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)

x=1/4

y = - 2

(1/4, - 2)

b

Step-by-step explanation:

4x - y = 3

y = -8x

substitute y = -8x into the first equation. Everywhere you see y put 8x

4x - y = 3

4x - (-8x) = 3

4x+8x=3

combine like terms

12x = 3

divide by 12

12x/12x = 3 / 12

x = 1/4

now we need to find y

y = - 8x

y = - 8 * 1/4

y = - 2
