Find the solution to the system of equations. x + 4y - 5z = -6
x + 4y. 42 = -1
x+ 5y - 42 3
A. X3, y = 4,25
B. A = 5, y = 3, zu 6
O C. ** 3, y 13, 2-14
O D. x4, y 5, z3

i believe that the answer is

b. y-1=-2(x-4)

hope this !

answer: idk wbu

step-by-step explanation:

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.

54/3 is 18 so 18 is your answer
