Question

Solve.

³+y+z
3x-2y+22-2
−2x−y+3z − −4
Enter your answer, in the form (z,y,2).
6

Answer 1

(2, -6, 1)

Explanation:

Multiplying the first equation by 2 yields 4x+2y-2z = -6.

Adding this to the second equation, we get 9x=18, and thus x=2.

From the third equation, we know z=1.

From the first equation, it follows that y = -6.
