i can't remember how to solve more than 2 simultaneous equations. how would i solve something with the following form:?? 3x+4y+2z=0 2x+18y-5z=3 5x-2y+8z=9 what are x, y, and z. this isn't an actual problem i have, so i don't care about the solution to that one (if it actually exists), i just want to know what the process is for solving three simultaneous equations. i feel so dumb for not remembering this. thanks!!
