Three System Equations( Don't just give answer show work so I can understand)?
2x + 3y + z = 17x - 3y + 2z = -85x -2y +3z = 5I tried it and no matter which variable I eliminate I cant get an answer. Solve by elimination. or:2x +
2x + 3y + z = 17
x - 3y + 2z = -8
5x -2y +3z = 5
I tried it and no matter which variable I eliminate I can't get an answer. Solve by elimination.
or:2x + 3y + z = 17x - 3y + 2z = -85x -2y +3z = 5I tried it and no matter which variable I eliminate I can't get an answer. Solve by elimination.
or:2x + 3y + z = 17x - 3y + 2z = -85x -2y +3z = 5Take #1 & #22x + 3y + z = 17-2x + 6y - 2z = 16 Multiplied everything by -2.---------------------- ADD0 ..... 9y - z = 33z = -9y - 33 Substitute this for z in #3 and one of the others and solve it as a problem with two unknowns.www.wolframalpha.com/input/?i=solve+2x+%2B+3y+%2B+z+%3D+17%2C+x+-+3y+%2B+2z+%3D+-8%2C+5x+-2y+%2B3z+%3D+5Bookmark the site to check all your homework.
