Which answer has a correct next step for this system? (Read all three answers carefully before selecting one!)

The variable is already isolated, so we've already solved the system.

The variable is already isolated for y, so we substitute 3x + 5 in the first equation like this:

3x + 4(3x + 5) = 3

The variable is already isolated for y, so we substitute 3x + 5 in the second equation like this:

3(3x + 5) + 4y = 3
