Question

If you were to use the substitution method to solve the following system, choose the new system of equations that would result if x was isolated in the first equation.
x + 6y + z = 2
x – 3y + 2z = –1
x + 5y + 3z = –4

Answer 1

x =2 -6y - z

Answer 2

11y + 4z = 6
2y + 5z = 3

y – 2z = 6
–8y – z = 3

3y + 3z = –3
11y + 4z = –6

–9y + z = –3
–y + 2z = –6


THESE ARE THE OPTIONS

Answer 3

I hate these because they force you to use methods you may not like to use

Answer 4

-9y + z = -3
-y +2z = -6

Answer 5

thanks:)
