Ionly want to know which one is an identity, a contradiction, or niether. solve each given equation and show your work. tell whether it has one solution, an infinite number of solutions, or no solutions, and identify each equation as an identity, a contradiction, or neither. (a) 6x+4x-6=24+9x (b) 25-4x=15-3x+10-x (c) 4x+8=2x+7+2x-20
