The sum of three numbers a, b, and c is 99. If we increase a by 6, decrease b by 6 and multiply c by 6, the three resulting numbers are equal. What is the value of b?
a + 6 = b-6 = 6c sooo a = b-12 c = 1/6 a = 1/6(b-12)
a + b + c = 99
b-12 + b + 1/6 (b-12) = 99
b= 52.153846 a = 40.153846 c = 6.69231
