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

anonymous · Answer

a. 2x – 3(4y + 13) = –29
b. 2(4y + 13) – 3y = –29
c. 2(–4y + 13) – 3y = –29
d. 2x – 3(–4y + 13) = –29
