If k=[-4 | 2, 6 | -3] and m=[2 | 8, -2 | 5] what is x when 2x -k = m
marshall27 [118]

Answer:

  x = [-1 | 5, 2 | 1]

Step-by-step explanation:

We assume your notation is used to describe 2×2 matrices.

Solve for x:

  2x -k = m

  2x = m + k . . . . add k

  x = (1/2)(m +k) . . . . multiply by 1/2

Fill in the values:

  x = 1/2[2+(-4) | 8 +2, -2+6 | 5+(-3)]

  x = [-1 | 5, 2 | 1]
