a. Candice is solving this system: 2x-1=3y 5(2x-1)+y=32 She notices that each equation contains the expression 2x−1. Can she substitute 3y for 2x−1? Why or why not?

Yes, because 3y=2x-1, so they are the same.

Yes, because they are on the same side of the equal sign.

Yes, because 2x-1 is in the second equation.
