Question 28704
1. Rewena's age = x-2
Gary's age = x


16 years before they were married:
Rewena = x-2-16
Gary = x-16
2(x-18)=x-16
2x-36=x-16
x=20

20-2=18


Hence Gary was 20 years old and Rowena was 18 years old.


2.
Rex's age = 3y+2-30
Mother's age = 3y
Father's age = 3y+2


Equation:
3y+2-30+3y=3y+2
6y-28=3y+2
3y=30
y=10


3(10)+2-30=2
3(10)=30
3(10)+2=32


Hence, Rex  is 2 years old.


3.Helston's age= x
Jason's age = 3x
In three years Jason's age= 3x+3
Three years of Helston's age = x+3
One year ago Helston's age = x+1
Equation:


6(x+3-x+1)=3x+2
6(4)=3x+3
24=3x+3
3x=21
x=7
3(7)=21


Hence, Jason is 21 years old and Helston is 7 years old.



4. Micheal's current age = x
x+10=2(x-10)
x+10=2x-20
-x=-10
x=10


Hence, Micheal is 10 years old.


5.Sister's age = x
Raymond's age = x+6
Four years from now Raymond's age= x+6+4
Four years from now Sister's age = x+4
equation:


2(x+4)=x+10
2x+8=x+10
x=2


2+6=8


Hence, Raymond is 8 years old and his siter is 2 years old.
