Answer: Albert's grand father is 50 years older that Albert this year.
Step-by-step explanation:
Let x represent Albert's age this year.
Let x represent Albert's grandfather age this year.
This year Albert and his grandfather's ages total to 64 years. This means that
x + y = 64- - - -- - - - - -1
In 3 years, Albert's grandfather will be 6 times as old. This means that
y + 3 = 6(x + 3)
y + 3 = 6x + 18
y = 6x + 18 - 3
y = 6x + 15
Substituting y = 6x + 15 into equation 1, it becomes
x + 6x + 15 = 64
7x = 64 - 15 = 49
x = 49/7
x = 7
y = 6x + 15 = 6 × 7 + 15
y = 57
The difference between their ages is 57 - 7 = 50 years
