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

A.2(–4y + 13) – 3y = –29
B.2x – 3(–4y + 13) = –29
C.2x – 3(4y + 13) = –29
D.2(4y + 13) – 3y = –29

what is x = to in the 2nd eqution?

amistre64 · Answer

b and c are out right of the bat

amistre64 · Answer

and since we have to subtract a 4y to get to x; id pick the one with a -4

amistre64 · Answer

but thats just taking the "test" as opposed to working out the problem :)
