May you please give us the actually question ?
-1 and 16/25
Negative one and sixteen twenty-fifths
Work backwards.
Start with z = 4.
Now deal with the middle equation
y + 3z = 11 Substitute z = 4 and solve for y
y + 3(4) = 11 Subtract 12 from both sides
y + 12 = 11
y + 12 - 12 = 11 -12 Combine terms on the left and right
y = - 1 Now use the top equation for x
z = 4 z still = 4
2x + 4(-1) +3(4) = 14
2x - 4 + 12 = 14 Solve 3z
2x + 8 = 14 Subtract 8
2x + 8 - 8 = 14 - 8 Combine
2x = 6 Divide by 2
x = 6/2
x = 3
Answer
x = 3
y = - 1
z = 4
The answer to that would be 0
Answer: second option
Step-by-step explanation:
Direct variation equation has the following form:
![y=kx](https://tex.z-dn.net/?f=y%3Dkx)
Where "k" is the constant of variation.
In direct variation when the variable "x" increases, the variable "y" increases in proportion to "x" and when the variable "x" decreases, the variable "y" decreases in proportion to "x".
You can observe in the table that when "x" increases, "y" increases, therefore it is a Direct variation.
