Question

HELP I JUST WANT TO FINISH GET MY CREDIT AND GRADUATE 70 POINTS HELP ASAP What are the values of x and y in the matrix subtraction below? [[- 20, 16], [4, 0], [9, - 6]] - [[- 5, 1], [- 6, 7], [0, 11]] = [[x, y], [10, - 7], [9, - 17]]

Answer 1

We want to solve the question below

We can see that a matrix was subtracted from another. In Addition or subtraction of matrix, we just add or subtract the element. So

We have in the first row

`\begin{gathered} -20-(-5)=x \\ -20+5=x_ \\ x=-15 \end{gathered}`

And

`\begin{gathered} 16-1=y \\ 15=y \\ y=15 \end{gathered}`

Hence x = -15 and y = 15, the first option is correct
