Look at the system of equations below.
4x-5y=3
3x+5y=13
a student makes this argument: elimination is the best method for solving this system because the y-coefficient in the first equation is the opposite of the y-coefficient in the second equation.
complete the student’s argument by explaining why substitution and graphing are less efficient methods than elimination for this system.
