Sara is 24 years younger than Joe. Six years ago she was half as old as he was. How old is he now?

• Pre-algebra -

present age:
Joe --- x
Sara --- x-24

Six years ago:
Joe ---- x-6
Sara --- x-24 - 6 = x - 30

x - 30 = (1/2)(x-6)
times 2
2x - 60 = x - 6
x = 54

Joe is now 54 , and Sara is now 30

check:
six years ago , Joe was 48 , and Sara was 24
Was he twice as old as Sara ??? YES
