Question 1106225
In three more years Michael’s grandmother will be six times as old as Michael was last year
g + 3 = 6(m - 1)
g + 3 = 6m - 6
g = 6m - 6 - 3
g = 6m - 9
:
 when Michael’s present age is added to his grandmother’s present age the total is 68 
m + g = 68
replace g with (6m-9)
m + 6m - 9 = 68
7m = 68 + 9
7m = 77
m = 11 yrs is M's age
then
g = 6(11) - 9
g = 66 - 9
g = 57 yrs is G's age

You should confirm this in both statements
