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 second equation.

2x – 3y – z = –1
x – 4y + 3z = –11
2x + 9y + 3z = –13

a)–11y + 5z = 21
y + 9z = 9

b)5y – 7z = 21
17y – 3z = 9

c) 7x – 13y = –14
8x = –16

d) –5x +5y = –8
–4x + 18z = –10

Answer 1

????

Answer 2
