Question

One more question about matrices and I'm done!! Sorry! ._.

I need to figure out how to solve matrix equations. I'm confuzzled.

Answer 1

For example, I need to solve this one:\[\left[\begin{matrix}4 & 8 \\ 2 & 5\end{matrix}\right]\left(\begin{matrix}x \\ y\end{matrix}\right)=\left(\begin{matrix}0 \\ 6\end{matrix}\right)\]

Answer 2

do u know how matrix multiplication works , or a dot product

Answer 3

another way is to take inverse of both sides, prolly not for ur lvl yet

Answer 4

This is all really new to me /: If anyone could walk me through just this one problem step by step it would probably give me a better understanding.

Answer 5

4 * x + 8* y = 0
2*x + 5*y = 6
are ur 2 equations to solve

Answer 6

Is it possible to solve those by putting them into a graphing calculator and finding the intersecting point?

Answer 7

[4 8 |0]
[2 5 |6]
get this in this form below
[1 0 | x]
[0 1 | y]

Answer 8

or just solve those 2 equations above from basic algebra
u have 2 functions and 2 unknown

Answer 9

4x + 8y = 0 ; x =-8y/4 =-2y ; sub x in other equation and solve
2x + 5y = 6
