3y+2z
x = 3 and y = 0
No.
-3y + z = 12
See definition of polynomial and monomials. You will see.
3x 3y + 6z = 12
Solve this system of equations. 5x+3y+z=-29 x-3y+2z=23 14x-2y+3z=-18 Write the solution as an ordered triple.
3y+2z
5y = 3y + 12 5y - 3y = (3y - 3y) + 12 2y = 12 y = 6
x = 3 and y = 0
what do you want to be solved?
No.
-3y + z = 12
4x+3y = 12 3y = -4x+12 y = -4/3x+4
See definition of polynomial and monomials. You will see.
2x + 3y = 12 x = 1.45, so 2 * 1.45 + 3y = 12 2.9 + 3y = 12 3y = 12 - 2.9 = 9.1 y = 9.1/3 = 3.0333... or 91/30 or 3 1/30.
The ordered triple is (x, y, z) = (1, -1, -2)
