Question

Find M Below.

3[5, 11, 1, -2, -1, 5]+M=[-2,-2,-4,5,5,-5]

Answer 1

mult the first matrix by 3

to get
[15, 33, 3, -6, -3, 15] + M = [-2, -2, -4, 5, 5, -5]

Answer 2

Now subtract the 1st matrix on both sides..

Answer 3

to get m alone

Answer 4

[15, 33, 3, -6, -3, 15]

Answer 5

M = [-2, -2, -4, 5, 5, -5] - [15, 33, 3, -6, -3, 15]

do you know how to subtract matrices?

Answer 6

m = [-2-15, -2-33, -4-3, 5 + 6, 5+ 3, -5-15]

m = [-17, -35, -7, 11, 8, -10]

Answer 7

[-17 -35 -7 11 8 -20]

Answer 8

chk the last one.......-5 -15 = -25

sorry I screwed it up too.

The rest look good

Answer 9

you good?

Answer 10

yes
