43 = 4 tens and 3 ones. (:
10 + 10 + 10 + 10 = 40
1 + 1 + 1 = 3
40 + 3 = 43
8*5=40
4*10=40
so the least number of hot dogs you can buy so that you can also buy a matching number of buns is 40.

Step-by-step explanation:
Eloise made these steps well:
Square root of negative 2x plus 1 - 3 = x
Square root of negative 2x plus 1 - 3 + 3 = x + 3
The error comes in the next step:
Square root of negative 2x plus 1 = x + 3
Square root of negative 2x plus 1 -1 = x + 3 - 1
Square root of negative 2x = x + 2
the number one is inside the root, therefore they can not be subtracted.
answer
error in the step:
Square root of negative 2x = x + 2
