solve the system. if there's no unique solution, label the system as either dependent or inconsistent.
2x + y + 3z = 12
x – y + 4z = 5
–4x + 4y – 16z = –20
a. (4, 1, 2)
b. (1, 4, 2)
c. inconsistent system (no solution)
d. dependent system (infinite number of solutions)

B (1,4,2)

Step-by-step explanation:

the easiest way to solve this complex equation:-

since x=1, y=4, z=2

the equation is

2x+y+3z= 12

x-y+4z=5

-4x+4y-16z=-20

2(1)+4+4(2)=12

1-4+4(2)=5

-4(1)+4(4)-16(2)

then

2+4+6=12

1-4=-3+8=5

-4+16= 12-32=-20

$97520

step-by-step explanation:

add 6% to the value she got from selling the house.

24

step-by-step explanation:

if it takes 8 pounds to make 12 divide 12 by 8 and you get 1.5, 1.5 x 16 = 24
