Use the substitution method to solve the system of equations. choose the correct ordered pair. y=4x 8x+y=18

(3/2, 6)

Step-by-step explanation:

y = 4x

8x + y = 18

this says y is 4x so you can replace y with 4x

8x + 4x = 18

12x = 18

/12      /12

  x  = 3/2

now sub x into y = 4(3/2)

y = 12/2

y = 6
