Question

64 is 4 times the difference between Sarah's age, a, and 44. Assume Sarah is older than 44.

Write an equation to determine Sarah's age (a).

Find Sarah's age.

Answer 1

60 years old

Explanation:

64=4(a-44)

64=4a-176

64+176=4a

240=4a

4a=240

a=240/4

a=60 years old

Answer 2

64 = 4*(a-44)

Sarah is 60

Explanation:

64 is 4 times the difference between Sarah's age, a, and 44.

Is means equals and difference is subtraction

64 = 4*(a-44)

Divide each side by 4

64/4 =4/4 (a-44)

16 = a-44

Add 44 to each side

16+44 = a-44+44

60 = a

Sarah is 60
