Question

Write an equation that represents the following:

The ages of two sisters are consecutive integers . The sum of the older sister's age and three times the younger sister's age is 61.

Answer 1

(o+y) + 3y = 61

to solve divide by 5 because there is 4 younger sister age + 1 for the older sister. 61-1=60. we subtract because the sister is older by 1 year

60/5=12 so the younger sister is 12

(13+12) + 36 = 61

Consecutive means in order like 3,4,5 or 11,12,13

Hope this helps
