Algebra forming expressions

Question

Beth is 3 years old than Alan

Clara is 2 years younger than Alan

Donna is 3 times Alan's age

Emma is half Alan's age

Fiona is 2 years younger than Donna

Georgia is twice Beth's age

Hannah is 4 years older than Fiona

Isabelle is 3 times Emma's age

Answer 1

Let B =Beth's age, C = Clara's, D= Donna's, E=Emma's, F= Fiona's, G=Georgia's, H= Hannah's, I=Isabelle's

 

B= A+3

C=A-2

D= 3A

E=1/2 A

F= 3A -2

G= 2 (A+3)

H= (3A-2) +4

I = 3 (1/2 A)

 

Sally, this is an idea how to set up your expressions. There's many ways to do it. Now if you have Allan's age you should be able to work through each expression and arrive at an age for all the people named. I hope this helps you understand the process.
