Question

What is the solution of the system of equations?

{-3x - 4y - 3z = -7

{2x - 6y + 2z = 3

{5x - 2y + 5z = 9

A. (5,-2,7)

B. (-5,2,7)

C.(5,2,-7)

D. No solution

Use a matrix to find the solution to the system of equations.

{-8x - 8y = -16

{6x - 9y = -108

A.(-6,8)

B.(6,8)

C.(8,-6)


Solve the system by elimination.

{-2x + 2y + 3z = 0

{-2x - y + z = -3

{2x+ 3y+ 3z = 5

D.(6,-8)

Answer 1

\left[x \right] = \left[ -18+\frac{3\,y}{2}\right][x]=[−18+​2​​3y​​] totally answer
