WebSolution. Write z= 4 3 , x= 1 1 , and y= 1 −2 for convenience. Then we know T(x)and T(y)and we want T(z), so it is enough by Theorem 2.6.1 to express z as a linear combination of x and y. That is, we want to find numbers a and b such that z =ax+by. Equating entries gives two equations 4=a+b and 3=a−2b. The solution is, a=11 3 and b= 1 3 ...

WebJun 9, 2024 · I did the following: $A.X = B$ Since $Det (A) ≠ 0$, $A$ is reversible. Then, I multiply on both sides of the equality to the left by the inverse of $A$. We obtain: $A^ {-1} .A.X = A^ {-1}.B$. Then, $X = A^ {-1}$. Now, since the inverse of a matrix is unique then the system has a single solution.
