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
11y + 4z = 6
2y + 5z = 3
y – 2z = 6
–8y – z = 3
3y + 3z = –3
11y + 4z = –6
–9y + z = –3
–y + 2z = –6

good lets replace x in the next equation by that x – 3y + 2z = –1 6y  z + 2 – 3y + 2z = –1 when you collect like terms, i see only one answer that has this result
