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 y is eliminated in the first and second equations, then the second and third equations.3x – y + 3z = 1 4x + y – 6z = 3 4x – 2y + 3z = –3

Answer 1

As a start: 7x - 3z =4 would be the result of eliminating y combining the first two equations.

Answer 2

12x -9z=3 eliminating y using the last two equations.

Answer 3

Do you have to ultimately solve this system?

Answer 4

x=1
z=1
y=5
