Brandon uses the steps below to solve the equation 15x + 6 = 14x + 5 using algebra tiles.
Step1: Add 14 negative x tiles to both sides
Step2: Add 5 negative unit tiles to both sides
Step3: The solution is x = 1
Which explains whether Brandon is correct?
A) Brandon is correct because he has the correct solution in step 3
B) Brandon is correct because he forms zero pairs to isolate the variable by using the lowest coefficient each time
C) Brandon is not correct because he should have performed step 2 before performing step 1
D) Brandon is not correct because he should have added 6 negative unit tiles to isolate the variable in step 2
