Question

The sum of Emma's age and her sister's age is 41 years. Emma is 11 years older than her sister. What is Emma's age, and what is her sister's age?

Answer 1

Answer:30

Explanation:

41=x+11

move 11 to the other side and change sign

41-11=x

30=x

x=30

Answer 2

Answer: the age of Emma is 26 years and the age of her sister is 15 years

Explanation:

b= a+11

a + a + 11 = 41

2a + 11 = 41

2a = 30

a = 15

put a back into the equation

b = 15 + 11

b = 26
