Question

I need to find the letters

Answer 1

Answer:

w = 21

x = 13

y = -11

z = -16

Step-by-step explanation:

Matrix subtraction is simply subtracting "corresponding" values e.g. row 1 column 1 value of one matrix and row 1 column 1 value of another matrix, and so on...

Thus, w = 17 - (-4) = 17 + 4 = 21

x = 12 - (-1) = 12 + 1 = 13

y = -3 -8 = -11

z = -2 -14 = -16

These are the values of w, x, y and z , respectively.
