Let's represent Joel's current age as J and his father's current age as F.

According to the first statement, in x years, Joel's father will be six times as old as Joel was last year. This can be represented as:

F + x = 6(J - 1)

According to the second statement, when Joel's age is added to his father's present age, the total is 68. This can be represented as:

J + F = 68

We can now solve these two equations simultaneously to find the values of J and F.

From the first equation, we can express x in terms of J and F:

x = 6(J - 1) - F

Substitute this expression for x into the second equation:

6(J - 1) - F + J + F = 68
6J - 6 - F + J + F = 68
7J - 6 = 68
7J = 74
J = 10.57 (approx.)

Now, substitute J back into the second equation to find F:

10.57 + F = 68
F = 57.43 (approx.)

Therefore, Joel is approximately 11 years old and his father is approximately 57 years old.

Let's assume that Joel's age now is x and his father's age now is y.

From the given information, we can create two equations:

1) y + 6 = 6(x - 1)
2) x + y = 68

Let's simplify the first equation:
y + 6 = 6x - 6
y = 6x - 12

Now, substitute this expression for y into the second equation:
x + (6x - 12) = 68
7x = 80
x = 11.43 (approximately)

Since Joel's age must be a whole number, let's assume it's 11.

Now, substitute x = 11 back into the equation y = 6x - 12:
y = 6(11) - 12
y = 57

Therefore, Joel's age now is 11 and his father's age now is 57.
