Solve the system of equations.
3x + 2y + 4z = 7
4x + 3y + 5z = 9
7x + 4y + 72 = 5
a. (x = -5, y = 3,2 = 4)
c.
(x = -3, y = 1, 2 = 6)
b.
(x = -6, y = 4, z = 5)
d. (x = -4, y = 2, z = 3)
select the best answer from the choices provided

3/6 chance

step-by-step explanation:

half of the nubers are odd numbers (1,3,5) which in that case if you would be told to simplify it would be 1/2

answer:

the answer is b) divide by -4 on each side and flip the sign.

step-by-step explanation:

we first need to start by dividing. this is because it is a multiplication problem to start.

we also need to make sure we flip the sign because any time you multiply or divide by negative numbers, the sign must be flipped.
