What is -12 = 12 ? I think it is one solution, but I'm not sure.
If you are talking about solving an equation, with the variable being eliminated and you are left with -12 = 12, then
that means there is no solution. When solving an equation, if the variable disappears and you are left with a false statement, such as -12 = 12, there is no solution. If the variable disappears and you are left with a true statement, such as 4 = 4, then there are infinite solutions. Ask the House
