Answer 1

Sandy --- x
Jay------- 2x
mike ----- 2x+2

"Mike is 7 years older than Sandy "
---> 2x+2 = x+7

x=5

check:
Sandy is 5
Jay = 10
Mike is 12

Is Mike 7 years older than Sandy? YES

Answer 2

I'm sorry but I don't understand that

Answer 3

All I did is to translate the English into Math

Let Sandy's age be x
"Jay is as twice as old as Sandy "
----> Jay's age is 2x

"Jay is 2 years younger than Mike"
---> Mike's age is 2x+2

"Mike is 7 years older than Sandy"
---> 2x+2 = x=7
