Huilan is years younger than Thomas. The sum of their ages is 81. What is Thomas's age?

Step-by-step explanation:

Let x = the age of Thomas

Let x + 6 = the age of Huilan

x + x + 6 = 70

2x + 6 = 70

2x = 64

x = 32 years

x+6 = 38 years

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
