Question 1186622
When asked what her age is, she said that seven years ago, she was eleven times as old as her daughter.
m - 7 = 11(d-7)
m - 7 = 11d - 77
m = 11d - 77 + 7
m = 11d - 70
 Now she is four times as old as her daughter.
m = 4d
replace m with 4d in the first equation
4d = 11d - 70
70 = 11d - 4d
70 = 7d
d = 70/7
d = 10 yrs is daughter's age
:
 How old is Aj's mom?
m = 4(10)
m = 40 yrs is Mom's age

:
Check in the first statement
40 - 7 = 11(10 - 7)
33 = 11(3)
