Question

Name (show your step) -15 24 21,2) 1. Simon has twin younger brothers. The sum of the ages of the three brothers is 48 and the difference between his age and the age of one of his younger brothers is 3. How old is Simon? B+b=48​

Answer 1

Simon's age is 18.

Explanation:

Let Simons age be s and the age of each twin be t.

s + 2t = 48

s - t = 3

Subtract the second equation from the first:

s - s + 2t - (-t) = 45

2t + t = 45

3t = 45

t = 45/3 = 15.

Now we find Simon's age by plugging t = 15 in the second equation:

s - t = 3

s - 15 = 3

s = 3 + 15 = 18.
