Is it possible to solve the following system by using substitution? Which method, substitution or elimination is more efficient? Complete the explanation.

braceleftze 3x − 2y = 11
x + 2y = 25
possible to use substitution. Solve the second equation for x to get x =
y + 25. Substitute x in the first equation and solve for y. Then substitute this value for y in either original equation to get a solution of (
). The elimination method is
efficient because there are
calculations and they are
to do.
