Two times Antonio’s age plus three times Sarah’s age equals 34. Sarah’s age is also five times Antonio’s age. How old is Sarah?
Let Sarah's age be s and Antonio's age be a. According to your question, 2a + 3s = 34 s = 5a substituting the value of s in eq. 1, 2a + 3(5a) = 34 = 2a + 15 a = 34 17a = 34 thus, a = 34/17 = 2 substituting the value of a is s, s = 5(2) = 10 Thus, Sarah's age is 10 years and Antonio's age is 2 years.
