Best ResponseYou've already chosen the best response.0We are multiplying row 1 by a number that will turn the first term into a negative of the equation underneath it. 3x +3/8 y 3/8z = 96/8 1x +1/8 y 1/8z = 32/8 3x + 2y 3 z = 36 x 3 y +2 z =14

Best ResponseYou've already chosen the best response.03x + 3/8 y 3/8z = 12 1x +1/8 y  1/8z =  4 3x +16/8y 24/8z = 36 x 24/8 y +16/8z =14   0 +19/8y 27/8z = 24 0 23/8y +15/8z = 28 and we end up with two equations of two variables that are easier to work with....

Best ResponseYou've already chosen the best response.0the way professor taught me is multiply equation (1) by 2 16x2y+2z=64 +3x=2y3z=36 equation (2) =19xz=100 which becomes equation (4)

Best ResponseYou've already chosen the best response.0your professor choose to eliminate the "y" variable; I simply choose to start at the front and aliminatte the "x" variable. Same rules, different variable.

Best ResponseYou've already chosen the best response.0his way keeps the fractions out :) but the process is the same. we use the "modified" equation to eliminate a variable from the other 2

Best ResponseYou've already chosen the best response.0:) lets use equation 1 since it looks the plainest and use it to "calibrate" the other 2. ok?

Best ResponseYou've already chosen the best response.0x + y + z =4 < what should we mulitply this bu to get rid 2x+4y+2z =4 of a variable in the bottom equation?

Best ResponseYou've already chosen the best response.0we want either a: 2x, or a 4y; or even a 2z... what variable you wanna destroy?

amistre64

Best ResponseYou've already chosen the best response.0x y or z.... just pick one so we can move ahead ;)

amistre64

Best ResponseYou've already chosen the best response.0good, we will destroy the "x" :)

amistre64

Best ResponseYou've already chosen the best response.0the top has an "x" and the bottom has an "2x. ___ x + 2x = 0..... what do we need to fill in the blank here?

Best ResponseYou've already chosen the best response.0x + y + z =4 < multiply everything in this top by (2) 2x+4y+2z =4 to get 2x 2y 2z =8 2x +4y +2z =4 ; now add them together.  0 +2y +0 = 4 ; wow, 2 variables with one shot lol

anonymous

Best ResponseYou've already chosen the best response.0i dont understand the question... yeah, thats the ticket :)

amistre64

Best ResponseYou've already chosen the best response.0so we get; 2y = 4; what does y equal since its all alone?

anonymous

Best ResponseYou've already chosen the best response.0better question why do we multiply by 2

amistre64
 5 years ago
Best ResponseYou've already chosen the best response.0becasue you decided to destroy the x variables...... and that meant that we needed to have a number such that: ___x + 2x = 0 ; zero means they are eliminated, destroyed, kaput right?

Best ResponseYou've already chosen the best response.0So, to move ahead... we came to the conclusion that both those variables vanished in the process, and we are left with 2y=4; whats y have to be?

amistre64
 5 years ago
Best ResponseYou've already chosen the best response.0good, write that down someplace...y = 2 its one of your answers :)

amistre64

Best ResponseYou've already chosen the best response.0Now we use equation (1) that you gave me and use it to eliminate "x" in the last one right? x + y + z = 4 x +8y 3z =34

amistre64

amistre64

Best ResponseYou've already chosen the best response.0x represents x.... 1 represents 1..... but what you a really asking is: isnt there an invisible 1 in front of those? and I say , yes. and so you say, then the number we need is 1; and I say correct :)

Best ResponseYou've already chosen the best response.0yeah thats exactly what i was thinking

amistre64
 5 years ago
Best ResponseYou've already chosen the best response.0then we can multiply everything in the top by (1)...which seems pretty pointless right? but thats what we do :) x + y + z =4 < multiply it all by (1) and we get. x +8y 3z =34 x+ y+ z =4 x+8y3z=34 < add em up  0 +7y 2z = 30

anonymous

amistre64
 5 years ago
Best ResponseYou've already chosen the best response.0why would we do that? 1616 2z = 3016 is true, but it gets us nowhere fast. if we "add" 16 to both sides we get: 16+16 2z = 30+16

amistre64

Best ResponseYou've already chosen the best response.0y = 2, z = 7 lets use these in any of the others equations, but equation 1 seems lonely and wants some attention...so we will use it :) x + y + z = 4 x +2 + 7 = 4 x + 5 = 4 x = 45 x = 1; y=2; z=7 is the solution to our equations.

amistre64
 5 years ago
Best ResponseYou've already chosen the best response.0you agree? we can double check by using these values in all the equations and seeing if the results are true...

Best ResponseYou've already chosen the best response.0x+y+z=4 < we know this ones good.... we used it to find x ...................................... 2(1)+4(2)+2(7)=4 2 8 +14 = 4 10 + 14 = 4 4 = 4 ..... its good there ........................................ (1)+8(2)3(7)=34 1 16 21 = 34 1421 = 34 35 = 34 is off.....
