Multiple Choice

You are a logistics coordinator comparing two different freight delivery cost models based on dd distance units. To find out if the costs will ever be exactly the same, you set up the equation 4(7d+18)=13(3d2)11d{}4(7d + 18) = 13(3d - 2) - 11d. After distributing and combining the variable terms, the dd terms completely cancel out, leaving the mathematically false statement 72=26{}72 = -26. What is the correct classification for this type of equation?
