Question 784496: In 7 years ted will be twice as old as he was 9 years ago. How old is Ted now

You can put this solution on YOUR website!
x= Ted's age now
x%2B7= Ted's age 7 years from now
x-9= Ted's age 9 years ago

The problem says (in words) that
x%2B7=2%2A%28x-9%29

This is how we could solve it:
x%2B7=2%2A%28x-9%29
x%2B7=2%2Ax-2%2A9%29
x%2B7=2x-18%29
x%2B7%2B18=2x-18%2B18%29
x%2B25=2x%29
x%2B25-x=2x-x%29
25=x
highlight%28x=25%29
Ted is 25 years old.
He was 25-9 = 16 years old 9 years ago.
He will be 25+7=32 years old in 7 years.
