Hello,

tabangi ko ani beh.. lisud jud kaayo. Waaaa kinsay maka solve ani using matrices?


(a) x - 3y + 7z = 6
4x + y = 7
2x + 3y + z = 9

(b) 3x - 5z = 1
2x + 3y = 6
x +y +z = 5

Thanks!

nowadays no sweat na jed ni nga problem sa algebra use the 991 ms nga series sa casio...solve lagi dayon ni imo problema...

if mangita imo teacher sa solution...hatagi lng sa calcu... :mrgreen: hehehe

[orick]

gamita lang ang solving by elimination or substitution.
ang answer mao ra gihapon kong gamitan ug matrix.
hehe

2x+2y=4xy
I remembered my classmate before when asked by our Algebra teacher -> 2 cows plus 2 goats, can you add the two?
he answered: yes ma'am, 4 animals. Hahahaha!

(a)  x  -  3y  +  7z = 6
    4x +   y           = 7
    2x +  3y  +   z  = 9

(b) 3x - 5z = 1
     2x + 3y = 6
    x +y +z = 5

kabaw ko unsay answer ani.. number gihapon!
unsaon mani? e-explain sa daw doomsweek..

naa koy mura'g solution sa second problem, di ko sure kun sakto ba. maulaw ta ko magpost kay basig sayup...hehehe dugaydugay na ko nag-algebra 8th grade paman seguro to... but maybe naay math expert diri, pakicheck nalang... nalingaw bya ko bisan di ko math person, but i do think math is fun, sometimes

3x - 5z = 1
2x + 3y = 6
x + y + z = 5

3 0 -5 1
2 3 0 6
1 1 1 5

3 0 -5 1
0 1 -2 -4
1 1 1 5

1 0 -5/3 1/3
0 1 -2 -4
1 1 1 5

1 0 -5/3 1/3
0 1 -2 -4
0 1 8/3 14/3

1 0 -5/3 1/3
0 1 -2 -4
0 0 14/3 26/3

1 0 -5/3 1/3
0 1 -2 -4
0 0 14 26

1 0 -5/3 1/3
0 1 0 -2/7
0 0 14 26

1 0 -5/3 1/3
0 1 0 -2/7
0 0 1 13/7

therefore, x = 1/3 + (5/3)z
y = -2/7
z = 13/7
