Answers

Solve for $x$ and $y$
$$
\left[\begin{array}{cc}{x} & {2 y} \\ {4} & {6}\end{array}\right]=\left[\begin{array}{cc}{2} & {-2} \\ {2 x} & {-6 y}\end{array}\right]
$$

In this cushion? Yes, so or x. And why on magics Ex white or six. Right? My drinks Well minus wicks minus six. No. As we know that, like quality off the Memphis defined as the at risking and be on equal if and only if they're the same damage and corresponding entries up. Oh, here. As we see that, my grace ex wife or six is equal. McChrystal minus two X minus six. You hear that Dimensional Bookman is You're right. Over time, though, definition or equality off mattresses you get X is equal and y is equal minus. I want simplifying regard. Why is equal to minus one and, um value? Oh, X. And why on who and minus one? Yes.

This question is asking us to find the values of X and y for the following matrix were given that too Times X Why X plus y an X minus y is equal to the matrix to negative for negative two and six. We must play out this constant. We get equation equivalent to two x two. Why and then you have two X plus y and two X minus Y is equal to to negative four. No, you have to in six. And if you recall when you have two matrix two matrices set equal to each other that have values A, B, C and D said equal to in order for it to be equal to another matrix or will say e f G and h the values a must be equal to E, he must be equal to f see must be equal, achy and D must be equal age. Therefore, we know that for our matrix two X must be equal to two to why most people donated four and then we have to X plus y must be equal to negative two and two x minus y must be you go to six selling for this. We see that X. If you divide this to over, is he gonna one? And why? If you divide negative four by two, is he gonna negative too? And if you play these values in for this bottom row of the Matrix, we find out that stays constant. We have to times X plus y or one minus two is equal to negative two. Where will find that this is two times negative one which is indeed equal to negative two. And if you do the same for this two x minus Y you go six, you have to times one minus negative, too. Does he go six or to times one plus two or three is equal to six and both of them are satisfied. Therefore, we can conclude that acts is equal to one. And why is negative two?

In discussion. Yeah, The sun. Oh, x a Why? All right, we consider the holy statement that is humor Diplomat. That's why expressway X minus way is equal. Magnus who? Minus wall minus true six. No, uh, equality off herpes. And did you didn't? As wicks? By who express right works. Wireless is equal. Metris, move minus Will minus six. No, we know by the definition of equality off matters number just A and B are equal if and only if they have the same dimension. And Martin. And that was wounding and result. So on observing are given night business. You can do that. The dimension of the baldness is school by. So from the definition of equality of renters you good, who x is equal only and you get executed. And why is equal minus four when we had a really gay Why is my minus does values? Uh, X equal one. And why was minus
