Answer:
Error: not
Solution:x=0 and 3
Step-by-step explanation:
We have to find the error and correct answer
Given:
Using the formula
Therefore, x=0 and x=3
But last step in the given solution
It is wrong this property is used when
then
Hence, the student wrote instead of
and solution is given by
x=0 and x=3
<h3>Answer:</h3>
(x, y) = (7, -5)
<h3>Step-by-step explanation:</h3>It generally works well to follow directions.
The matrix of coefficients is ...
Its inverse is the transpose of the cofactor matrix, divided by the determinant. That is ...
So the solution is the product of this and the vector of constants [-6, -50]. That product is ...
... x = (3·(-6) +(-4)(-50))/26 = 7
... y = (5·(-6) +2·(-50))/26 = -5
The solution using inverse matrices is ...
... (x, y) = (7, -5)
