Question

Tina's age is 4 years less than 3 times her niece's age. If her niece's age is x years, which of the following expressions best shows Tina's age?

Answer 1

x= 3x - 4..................

Answer 2

"4 years less" means something - 4
"3 times her niece's age" means 3x, considering x if her niece's age.
4 less than 3x = 3x - 4
So the answer is that the expression 3x - 4 can be used to represent this problem.
