Step-by-step explanation:
I assume the question is asking for Eric's grandfather age now.
Let Eric's age now be x. Then Eric's grandfather age now is (x + 55).
In 7 years, Eric's age will be (x + 7) and Eric's grandfather age will be (x + 62).
We know that (x + 62) = 6(x + 7).
x + 62 = 6x + 42
5x = 62 - 42 = 20
x = 4.
Answering the question: Eric's grandfather age now is (4 + 55) = 59 years old.
