Sweets, candy

Grandfather gave out sweets to four children. At the last moment, two more children came, so to have them all the same, each of the four children had to give back four candies. How many candies did grandfather have in total?

Final Answer:

x =  48

Step-by-step explanation:

$$\begin{gathered} x=4b \\ x=4(b-4)+2\cdot (b-4) \\ 4b=4(b-4)+2\cdot (b-4) \\ 4\cdot b=4\cdot (b-4)+2\cdot (b-4) \\ 2b=24 \\ b=\frac{24}{2}=12 \\ b=12 \\ x=4\cdot b=4\cdot 12=48 \end{gathered}$$
