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

2x – 3y = –29
x + 4y = 13 (5 points)

2(4y + 13) – 3y = –29
2(–4y + 13) – 3y = –29
2x – 3(4y + 13) = –29
2x – 3(–4y + 13) = –29

Question

If you were to use the substitution method to solve the following system, choose the new equation after the expression equivalent to x from the second equation is substituted into the first equation.

2x – 3y = –29
x + 4y = 13 (5 points)

 	
	2(4y + 13) – 3y = –29
	2(–4y + 13) – 3y = –29
	2x – 3(4y + 13) = –29
	2x – 3(–4y + 13) = –29
