f + L = 504
f = 2 L/7
so
2 L/7 + 7 L/7 = 504
9 L/7 = 504
L = 392
f = 2 * 392 / 7
so
f = 112
(112 + ff ) (4/3) = L
Solve for L
We know that:
f + L = 504
And:
f = 2L/7
Substituting the second equation into the first equation, we get:
2L/7 + L = 504
Multiplying both sides by 7, we get:
2L + 7L = 3528
Combining like terms, we get:
9L = 3528
Dividing both sides by 9, we get:
L = 392
Now we can use the equation:
(112 + ff) (4/3) = L
Substituting the value we found for L, we get:
(112 + ff) (4/3) = 392
Multiplying both sides by 3/4, we get:
112 + ff = 294.67
Subtracting 112 from both sides, we get:
ff = 182.67
Therefore, the value of L is 392 and the value of ff is 182.67.
