Charles is solving a linear equation. The equations is 12(y+2)=6(2y+4).

His last two steps are:

12y+24=12y+24

24=24

Select the statement that correctly interprets the solution.

• The solution is y=1

• The solution is point (24,24)

• There are infinite solutions since 24=24 is a true statement.

• There are no solutions because 24=24 is a true statement.
