Answer:
B) No Unique Solutions
Step-by-step explanation:
Given:
![z=x+5y-14](https://tex.z-dn.net/?f=z%3Dx%2B5y-14)
![-2y=-4\\y={-4}{-2}=2](https://tex.z-dn.net/?f=-2y%3D-4%5C%5Cy%3D%7B-4%7D%7B-2%7D%3D2)
![3x+y-3z=14](https://tex.z-dn.net/?f=3x%2By-3z%3D14)
now we now the value of y = 2 so we will substitute in equation ![z=x+5y-14](https://tex.z-dn.net/?f=z%3Dx%2B5y-14)
![z=x+5\times2-14\\z=x+10-14\\z= x-4](https://tex.z-dn.net/?f=z%3Dx%2B5%5Ctimes2-14%5C%5Cz%3Dx%2B10-14%5C%5Cz%3D%20x-4)
Now, We have value of y=2 and value of
Substituting in both the value in equation ![3x+y-3z=14](https://tex.z-dn.net/?f=3x%2By-3z%3D14)
![3x+2-3(x-4)=14\\3x+2-3x+12=14\\14=14](https://tex.z-dn.net/?f=3x%2B2-3%28x-4%29%3D14%5C%5C3x%2B2-3x%2B12%3D14%5C%5C14%3D14)
which means that the equation has Infinite solutions.
Answer: b+95+34=180, b+129=180, 51
Step-by-step explanation:
b+95+34=180 works because the angles add to form a straight angle.
From this, we can obtain b+129=180 by adding the two constants.
Subtracting 129 from both sides, we get b=51.
