Question 1134466
Mother's age = x
Mary's age = y

Present: x = 4y           Mother is four times old as Mary
Past:   x-5 = 7(y-5)      Both age needs to be subtracted from five first.

4y-5=7y-35
 -3y=-30
  y=10

x=40 and y=10

Mother's age in five years = 40+5 =45 years old
Mary's age in five years = 10+5 = 15 years old
