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.

(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

Step-by-step explanation:

true statements:

a) x + y = y + x   ⇒ commutative property of addition

b) (x * y) * z = x * (y * z) ⇒ associative property of multiplication

d) (x + y) + z = x + (y + z) ⇒ associative property of addition

false statements:

c) x - y = y - x   should be: x - y = - y + x

e) (x - y) - z = x - (y - z) should be: (x - y) - z = x - (y + z)
