Ana's age is 8 years less than 4 times her sisters' age write an expression for Ana's age how old is Ana if her sister is 5 years old??

Answer 1

Ana's age is 12

Here's why:
Her sister is 5
x = Ana's age
Ana is 4 times - 8

5 x 4 - 8 = x PEMDAS
5 x 4 = 20
20 - 8 = x
x = 12

Answer 2

I think Ana is 12 years old:
5 x 4 - 8 = 12.
