[tex]AB+12=DC+12~(Given)\\\\AB+12-12=DC+12-12~(Subtract~12~on~both~sides)\\\\AB=DC~(Simplify)[/tex]

Answer:

AB = DC

Step-by-step explanation:

AB + 12 = DC + 12

To find AB, we can subtract 12 from both sides (this leaves AB on its own):

  • AB + 12 - 12 = DC + 12 - 12 (Now, we can simplify)
  • AB = DC
