Question

Joan and amber have a combined age of 34 if amber is 2 years less than twice Joan's age how old is each person

Answer 1

Joan :12 years old.
Amber : 22 years old.

Answer 2

j = Joan
a = amber
a = 2j - 2

j + a = 34

j + 2j - 2 = 34
3j - 2 = 34
+2 + 2
3j = 36
j = 12

j + a = 34
12 + a = 34
-12 -12
a = 22

Joan would be 12 years old and Amber would be 22 years old.
