X = 7. Because both lines equal the same so it has to equal 75 
11 x 7 = 77 
77-2 = 75 
X = 7

The product that is  undefined is known a CD, where C is a 3 x 1 matrix and D is a 1 x 2 matrix.
<h3>What is the matrix about?</h3>
Looking at the product of matrix, note that to multiply  the two matrix, the column of the first matrix needs to have the same or equal to the row of the 2nd matrix.
And in this case (propensity), it is not satisfied by the first  option because:
C =  3 x 1  and 
O= 2 x 1  matrix
In this case CD is therefore undefined.
So we can say that The product that is  undefined is known a CD, where C is a 3 x 1 matrix and D is a 1 x 2 matrix.
