Question

Which matrix equation has the solution X = [3 / 5 ]

Answer 1

write any 2*2 matrix A
multiply it by [3 5] and call the b

then
Ax=b

Answer 2

Yes I cant figure out what problem that would be

Answer 3

make up a 2 x 2 matrix

Answer 4

any matrix you want..and tell me what it is

Answer 5

[2 3]
[4 6]

Answer 6

what is
[2 3]
[4 6]
multiplies by
[3]
[5]
?

Answer 7

Do you want me to multiply by 3 and 5? I dont understand the question

Answer 8

is [3/5] in your question a vector?

Answer 9

Yes it is

Answer 10

ok
call that vector x
call your matrix A
what is Ax?

Answer 11

multiple matrix A with vector x

Answer 12

do you know how to do this?

Answer 13

no I dont I just started this chapter

Answer 14

I don't see how they expect you to solve this if you don't know how to multiply
your question is this

ok lets talk about numbers not vectors for a second
give me an equation of the form ax=b
where x =3 is a solution
let a = 3
3*3 = 9
so
b=9
3x=9
is an equation of that form

Answer 15

o ok

Answer 16

what would be the next step?

Answer 17

well you need to learn to multiply matricies with vectors, I would google that

Answer 18

matrices
