Answer:
Explanation:
Let Angelo's present age be x and his grandfather's age be y.
x+y=68
y=68−x
In three more years, his grandfather will be six times as old as ANgelo last year :—
y+3=6(x−1)
y+3=6x−6
y+3+6=6x
y+9=6x
68−x+9=6x {y=68−x}
6x+x=68+9
7x=77
x=77÷7=11
Thus, Angelo's age = x = 11 years
And, Angelo's grandfather's age =
y = 68 - x = 68 - 11 = 57 years
Angelo's age is 11, his grandfather's age is 57
