Answer:
elijah is 18yrs old, rozen is 9yrs old and klare is 4yrs old.
Step-by-step explanation:
Since rozen's age is connected to her sisters age we will make his age as the center of equation. Let R stand for Rozen's age.
R(2)+R+(R-5)=31
all you will do is to think of a number that will satisfy the equation.
if rozen is 8 years old then her sister(elijah) will be 16yrs old and klare will be 3 years old which is wrong because...
R(2)+R+(R-5)=31
8(2)+8+(8-5)=31
16+8+3=31
27=31
the number doesn't satisfy the equation.
but if rozen is 9 years old the equation will be...
R(2)+R+(R-5)=31
9(2)+9+(9-5)=31
18+9+4=31
31=31
corect.
