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 first equation is substituted into the second equation.

12x – y = –4
4x – 3y = –6

a 4x – 3(–12x – 4) = –6

b 4x – 3(12x + 4) = –6

c 4(12x + 4) – 3y = –6

d 4(–12x – 4) – 3y = –6

Answer 1

b

Answer 2
