Question 1082590
write an equation for each statement
 Today, Maria's age is six times than Ana's age ten years ago.
m = 6(a-10)
distribute
m = 6a - 60
 Five years from now, Ana's age will be the same as Maria's age ten years ago.
a + 5 = m - 10
a = m - 10 - 5
a = m - 15
or
m = a + 15
therefore
6a - 60 = a + 15
6a - a = 15 + 60
5a = 75
a = 75/5
a = 15 yrs is Ana's age
 How old is Maria 
m = 15 + 15
m = 30 yrs is Maria

Check this using the statement
"Five years from now, Ana's age will be the same as Maria's age ten years ago."
15 + 5 = 30 - 10
