Find the values of the variables for which the statement is true, if possible.
Two matrices are equal if they are the same size and is corresponding elements, position by position, are equal.
These matrices are the same size, 2×2.
Since these two matrices are equal, corresponding elements must be equal. So for w we get the following equation.
w + 6 = 1
Therefore, w = – 5. In a similar way we get x = -8.
In the same manner the other variables can be found.
y = 8
z = 4.
