Jon has to choose which variable to solve for in order to be able to do the problem below in the most efficient manner. 6x+ 3y - 27
5x+ 2y - 21
Which variable should he choose so that he can use substitution to solve the system?
O Jon should solve for y in the first equation because the coefficients can be reduced by a common factor to
eliminate the coefficient for y.

Jon should solve for x in the first equation because the coefficients can be reduced by a common factor to
eliminate the coefficient for x.
Jon should solve for y in the second equation because the coefficients can be reduced by a common factor to
eliminate the coefficient for y.
