Answer: (0.5,2.8)
Step-by-step explanation:
So first we need to calculate the imaginary numbers in this question, by using a simple matrix formula:
Ax=b, where A is an m×n matrix, b is a vector in Rm, and x is a vector whose coefficients x1,x2,…,xn are unknown.
We can conclude that the vector one in this case is 0.5.
From there we can simply substitute in the first vector in xn. Then use the equation x3+y3+z3=k. To finally conclude the answer as 2.8
So the final answer is 0.5,2.8
