hey /sci/
fill in the operators + - x or / rounding is not allowed..
8 ? 8 ? (5 ? 3) = 4
>>7921791
8 - 8 / (5-3) =
8 - 8/2 =
8-4 =
4
can anyone help me solve this i am having anxiety over this
7x-3y+2z=0
4x-4y-z=2
5x+2y+3z=1
if you can show work that would be great
8 - 8 / (5 - 3) = 4

Use GauB
>>7921798
Gauss elimination. Just google it
>>7921798
x =1
y=1
z=-2
subtract equations to eliminate variables.
>>7921802
i have i know the steps but i always have trouble on which one's to eliminate
>>7921803
can you tell me which two i need to start out with and what letter to eliminate first the rest i can do
bump for help
can anyone help like i said just need to know what two to start with and if i have to eliminate x y or z that is it

instead of wasting time writing out the equations you should do it as a matrix and solve by rref

Are you 12

The order doesn't matter, as long as things cancel out
