Using cramer's rule, find values of x,y & z respectively if


Answers

solve each system of equations using Cramer's Rule if it is applicable. If Cramer's Rule is not applicable, say so. $$ \left\{\begin{aligned} x+y-z &=6 \\ 3 x-2 y+z &=-5 \\ x+3 y-2 z &=14 \end{aligned}\right. $$

Today. We're going to solve from the number 14. Yeah. D equals one minus one three 20 minus two. Toe minus four is determined. Value will be zero, then these affects X this. Determine whether we need to find zero minus one toe. Zero. Too little little toe foot. This valley will be zero. Liza, It's white. One zero No. Three 00 minus 20 minus four. This determined value will be zero. These are existed one minus one zero. The toe zero minus two. Toe zero. Which way will be zero? Cramer's rule says that if all determinants are zero, the system has infinite solution. Thank you.

They were going to solve problem number 41. Yeah. D equals one minus two. He three one minus two. Then tu minus 46 which likely will be zero. These effects executes zero minus two 30 01 minus two zero minus four. Six. Which, while there will be zero, these effects y equals Why? Zero 30 minus two 20 six, which is equal to zero. These affect the vehicle's one minus two zero 310 tu minus 40 which, where I live is zero. So Cramer's rule says that if all determinant zero, the system has infinite solution. Thank you.

Today we're going to solve problem number 39 Hit because one so minus one tu minus 41 minus two. Toe minus three, which values 22 then the some X X equals zero to minus a lot. Zero minus 41 zero minus street Its values. Zero. These ethics vehicles determinant off one zero minus one, 201 minus 20 minus three. Which values zero determinant zik to find this one toe zero to Linus full a little minus two toe zero. This determinant valley will be zero Sure X equals the X body, which is a call to little but by 20 which is durable. Why? Because the everybody which is zero by 22 which is zero the articles Dessert body zero by 22 which is zero. That's the end off a question. Thank you.

Today we are going to solve a problem. Number that three here. What do you think, Drama? So we need to find deep the x the way. And is that so? D will be determined off 11 minus one three minus two one one three minus two. So which values? Minus street, then deep X, its value determined values six one minus one minus five minus 21 14, three minus two. If we sold this determinant, you will get minus tree. The way will be one six minus one than three minus five. One one, 14 minus two. So this value will be minus nine. Then, De Zed This that is 11 six three minus two minus phi one three 14. It's where lose six. Then we need to find X X equals B X by the which is minus three divided by three which is minus one y equals divide by deep, which is minus nine the other by minus three Produce, they're Deco's these air developed by what? Which is six year old by minus three, which is minus two. That's the end off a question. Thank you.
