Evaluate x and y if `{:[(5,-3),(x,4)]:}={:[(y-3,-3),(2x+2,4)]:}`.

Text Solution

Verified by Experts

These two matrices are equal if `y-3=5andx-2x+2`. Therefore, y=8 and x=-2.
If `r=1`, the matrix is called a row matrix. If `c=1`, the matrix is called a column matrix. If r=c, the matrix is called a square matrix. The numbers from the upper left corner to the bottom right corner of a square matrix from the main diagonal. Scalar multiplication takes place ehen each number in a matrix is multiplied by a constant If two matrices are the same size, they can be added or subtracted by adding or subtracting cor responding entries.
