Question

Eric's grandfather is 55 years older than Eric. Seven years from now, Erica grandfather will be 6 times as old as Eric is at that time. How old is Eric's grandfather

Answer 1

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.
