Is it possible to solve the following system by using substitution? Which method, substitution or elimination is more efficient? Complete the explanation. 3x − 2y = 11 x + 2y = 17 possible to use substitution. Solve the second equation for x to get x = y + 17. 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.
