------------------------------------------------ Ed is 7 years older than Ted. Ed’s age is also 3 times Ted’s age. How old are Ed and Ted?

Answer :

Answer:21

Step-by-step explanation:

X-Ted

X+7-Ed

X+7=3/2x (subtract 7 from both sides)

X=3/2x-7 (subtract 3/2x from both sides)

-1/2x=-7 (multiply both sides by (-2))

X=14 (this is Teds age)

14+7=21 (this is Ed’s age)
