If you were to use the elimination method to solve the following system, choose the new system of equations that would result after the variable z is eliminated in the second and third equations, then the first and second equations.

5x + 2y + z = -2
3x + 4y + 3z = 2
-4x - 3y - 3z = 1

Question

If you were to use the elimination method to solve the following system, choose the new system of equations that would result after the variable z is eliminated in the second and third equations, then the first and second equations.

5x + 2y + z = -2
3x + 4y + 3z = 2
-4x - 3y - 3z = 1

anonymous · Answer

3x + 4y + 3z = 2 
-4x - 3y - 3z = 1
----------------
 -x +y +0 = 3

y = 3+x

anonymous · Answer

A. 5x + 2y = -2
3x + 4y = 2	
	 B. -x + y = 3
-12x - 2y = 8	
	 C. 5x + 2y = -2
-12x - 2y = 8	
	 D. x - y = -3
3x + 4y = 2
