A and B
3000x + 24000 = 2400x + 30000
3000x - 2400x = 30000 - 24000
600x = 6000
x = 6000/600
x = 10 years A and B are the same
B and C
2400x + 30000 = 2000x + 36000
2400x - 2000x = 36000 - 30000
400x = 6000
x = 6000/400
x = 15 years B and C are the same
3000x + 24000 = 2400x + 30000
3000x - 2400x = 30000 - 24000
600x = 6000
x = 6000/600
x = 10 years A and B are the same
B and C
2400x + 30000 = 2000x + 36000
2400x - 2000x = 36000 - 30000
400x = 6000
x = 6000/400
x = 15 years B and C are the same

So,
Let's translate this into mathematical form.
x - y = 9
x + 2y = 27
Elimination by Addition
Divide both sides of the second equation by 2
Add the two equations together
Multiply both sides by
Substitute
15 - y = 9
Subtract 15 from both sides
-y = -6
y = 6
Substitute
15 - 6 = 9
9 = 9 This checks.
15 + 2(6) = 27
Distribute
15 + 12 = 27
27 = 27 This also checks.
S = {(15,6)}

you have to find the common denominator for the 2 fractions.
leave 1/6 the same and turn ½ into 3/6.
then you can add 1/6+3/6 and get 4/6
then divide the numerator and the denominator by 2 any get ⅔
so ⅔ is your answer
Hope I helped :)

Jennifer has two pennies. She flips both pennies 105 times each. How many times can she expect both pennies to come up heads simultaneously?
Assuming I have correctly interpreted your question,
The probability both coins come up heads is
Thus the expected number of simultaneous heads is 105/4 or 26.25
