Step-by-step explanation:
Answer: x= -2 and y= -3.
Step-by-step explanation:
The given system of equations :
4x-7y=13 ...(i)
4x + 7y = -29 ....(ii)
By Elimination method, Eliminating (ii) from (i) , we get
![-7y-7y=13-(-29)\\\\\Rightarrow\ -14y=13+29\\\\\Rightarrow\ -14y=42\\\\\Rightarrow\ y=\dfrac{42}{-14}\\\\\Rightarrow\ y=-3](https://tex.z-dn.net/?f=-7y-7y%3D13-%28-29%29%5C%5C%5C%5C%5CRightarrow%5C%20-14y%3D13%2B29%5C%5C%5C%5C%5CRightarrow%5C%20-14y%3D42%5C%5C%5C%5C%5CRightarrow%5C%20y%3D%5Cdfrac%7B42%7D%7B-14%7D%5C%5C%5C%5C%5CRightarrow%5C%20y%3D-3)
Now, Adding (i) and (ii), we get
![8x=-16\\\\\Rightarrow\ x=\dfrac{-16}{8}\\\\\Rightarrow\ x=-2](https://tex.z-dn.net/?f=8x%3D-16%5C%5C%5C%5C%5CRightarrow%5C%20x%3D%5Cdfrac%7B-16%7D%7B8%7D%5C%5C%5C%5C%5CRightarrow%5C%20x%3D-2)
Hence, the solution is : x= -2 and y= -3.
The answer is B (ie. 1^2 = 1, 2^2 = 4...)
