Question

If you were to use the substitution method to solve the following system, choose the new equation after the expression equivalent to y from the second equation is substituted into the first equation.

2x – 7y = 4
3x + y = –17

Answer 1

2(3x – 17) – 7y = 4

2(–3x – 17) – 7y = 4

2x – 7(3x – 17) = 4

2x – 7(–3x – 17) = 4
