Question

Solve the system, or show that it has no solution. (If there is
no solution, enter NO SOLUTION. If there are an infinite number of
solutions, enter the general solution in terms of *x*, where
*x* is any real number.)

x | + | 3y | = | 9 |

4x | + | 12y | = |
4 |

(x,y) ________

Answer #1

Solve the system, or show that it has no solution. (If there is
no solution, enter NO SOLUTION. If there are an infinite number of
solutions, enter the general solution in terms of x, where x is any
real number.) 10x + 4y = 14
15x + 6y = 21

b) No solution
c) Infinite number of solutions

Solve the system of linear equations. If the system has an
infinite number of solutions, set w = t and solve for x, y, and z
in terms of t.)
x + y + z + w = 6
2x+3y - w=6
-3x +4y +z + 2w= -1
x + 2y - z + w = 0
x, y, z, w=?

1) Solve by Substitution.
{x+2y=−1
{-6y=3+3x
a) One solution:
b) No solution
c) Infinite number of solutions
2) Solve by Substitution
{4x+y=−15
{2y=-27-8x
a) One solution:
b) No solution
c) Infinite number of solutions
3) Solve the system by elimination.
{−x−2y=4
{2x+2y=-8
a) One solution:
b) No solution
c) Infinite number of solutions

Solve the system using either Gaussian elimination with
back-substitution or Gauss-Jordan elimination.If the system has an
infinite number of solutions, express x, y, and
z in terms of the parameter t.)
3x + 3y + 9z = 6
x + y + 3z = 2
2x + 5y + 15z = 10
-x + 2y + 6z = 4
(x, y, z)
= ?

A: Determine whether the system of linear equations has one and
only one solution, infinitely many solutions, or no solution.
3x - 4y = 9
9x - 12y = 18
B: Find the solution, if one exists. (If there are infinitely
many solutions, express x and y in terms of parameter t. If there
is no solution, enter no solution.)
(x,y)= ?
