"4x minus 5y equals 3 line break 3x plus 5y equals 13"
How about just typing:
4x - 5y = 3
3x + 5y = 13
Don't the y's have opposite coefficients ?
Wouldn't just adding them "eliminate" them?
Just for fun, you should try the other two methods and compare
the steps and the amount of work.
Look at the system of equations below.
4x minus 5y equals 3 line break 3x plus 5y equals 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.
