Question

Sarita has to solve the problem below for homework.

2 x + 3 y = 25. 4+ 2 y = 22.



Which variable should she choose to solve for so that she can use substitution to solve the system?


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


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


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


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