Hello there! The answer to your question is 'Sarah is 21 years old.'
Need an Explanation?:
So twice Sarah's age is equal to bob's age, which is 42. To solve, set up an equation that looks like this: (s = Sarah's age)
2s = 42
Solve for S. To do this, divide both sides of the equation by 2.
You get s = 21.
This means Sarah is 21 years old.
I hope this helps, and have a great day! Please don't hesitate to ask if you need more help with this specific question!
