To solve the equation 12x + 12 = 1,212, Martina first subtracted 12 from both sides of the equation. Theo, on the other hand, first factored 12 from both of the terms on the left side of the equation. If Martina and Theo both continue with their solutions, using the least number of steps possible, which of these is a valid argument?
Martina's solution is better because Theo's solution cannot work.
Martina's solution is better because it contains fewer steps.
Theo's solution is better because it contains fewer steps.
Theo's solution is better because it contains fewer steps.
