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

y=x+9
