Hey Brian! For some reason Im having trouble with the system:

3x + 2y + z = 7
5x + 5y + 4x =3
3x +2y +3z =1


someone said to add so i aded the 1st and 3rd equation and got x= -3, but now i dont know what to do and im stuck?

How do you know what number to multiply the whole equation by? Would it be the LCD?

[dismasmalembeka]

x+5y-3z=-9
2x-3y-z=19
3x+4y+z=-13 I need your help with this problem Brian McLogan please

How do you do 160x+1100y+90z
105x+805y+30z
X + Y = 256

Please help me to solve 2x_y+z=3 x+2y_z=1. 5x-5y+4z =8
