Respuesta :

Answer: consistent, independent; one

Step-by-step explanation:

Eliminate one variable.

4(x+5y+7z=13)——- 4x+20y+ 28z= 52 (Multiply equation 2 by 4)

Subtract

Write the 2-by2 system.

17y+22z=27

-30y+8z=46

Eliminate y and solve for z

Use one of the equations in the 2-by-2 and solve for y
