-
? = -3, ? = −1, ? = -5
-
? = -3, ? = −1, ? = 5
-
? = 3, ? = −1, ? = 5
-
? = 3, ? = −1, ? = -5
That's Correct!
It's Wrong!
The given system of equations can be solved by substitution or elimination method. By substituting the value of y from the second equation into the first equation, we get 2x + 4(4 - z) - z = -3. Simplifying this equation gives 2x - 3z = -19. By substituting the value of y from the third equation into the second equation, we get -2 + z = 4, which gives z = 6. Substituting the value of z into the first equation, we get 2x + 4(4 - 6) - 6 = -3, which simplifies to 2x - 14 = -3. Solving this equation gives x = 3. Therefore, the correct answer is ? = 3, ? = -1, ? = 5.
