Which answer has a correct first step for this system:

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

The variable is already isolated for y, so we substitute it in the first equation and solve for x

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

Free sha vaca doo

The variable is already isolated for y, so we substitute it in the second equation and solve for x

y = 3(3x + 3y) = 3
