Question

Sara is two years older than her brother. The sum of their ages is 29.

a. Write an equation

b. How old is Sara?

c. How old is Sara's brother?

Answer 1

You really should be able to do this ....

brother's age ---- x
Sara is two years older , so her age is x+2

"sum of their ages is 29"
sum --- +
their ages ---- I defined them for you
is ---- =

Now form the equation, and solve it.
Let me know how it worked out for you

Answer 2

I get the problem. It's the answer i don't get.

So I did x+(x+2)=29
2x+2=29
2x=27
x=13.5

So Sara would be 15.5 years old.
So is it okay that there is a decimal or should I change it to a fraction.

Answer 3

x=13.5
