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.
8x – y = –9
4x – 3y = –22
Answer

4x – 3(–8x – 9) = –22

4x – 3(8x + 9) = –22

4(8x + 9) – 3y = –22

4(–8x – 9) – 3y = –22

Answer 1

the second is right

Answer 2

4x – 3(8x + 9) = –22

Answer 3

thanks boys
