Grandfather 17981

Today, my grandfather is four times older than his grandson. Two years ago, my grandfather was six years younger than five times his grandson's age. How old is your grandson today?

Correct answer:

v =  14

Step-by-step explanation:

$$\begin{gathered} d=4v \\ d-2=-6+5(v-2) \\ 4v-2=-6+5(v-2) \\ 4\cdot v-2=-6+5\cdot (v-2) \\ v=14 \\ v=\frac{14}{1}=14 \\ v=14 \\ \text{ Verifying Solution: } \\ d=4\cdot v=4\cdot 14=56 \end{gathered}$$
